The eight environmental factors effecting the rate of respiration are: (1) oxygen content of the atmosphere (2) effect of temperature (3) effect of light (4) effect of water contents (5) effect of respirable material (6) effect of carbon dioxide concentration (7) protoplasmic conditions and (8) other factors. Numerous factors determine exchange rates many of these factors are related to the trading relationship between two countries remember, exchange rates are relative, and are expressed as a. =factors that affect reaction rate= the following factors can affect the rate of a reaction collision theory can be used to explain their affect. A key factor affecting the growth of the population is the death, or mortality, rate just as the birth of new people increases the population size, deaths decrease it the factors that affect the mortality rate include the availability and affordability of quality health care and lifestyle habits – for example, whether they smoke or do. Factors that have an impact on crime rates objectives or aim at the end of this lecture, you should be able to: a) identify and discuss factors that affect crime rate trends b) suggest possible solutions to addressing the problem of crime in the society,.
Factors that affect evaporation include the concentration of the evaporating substances in air, temperature, air pressure, the rate of airflow and surface area the heat of the sun facilitates the evaporation process, which is important in the water cycle. There are many factors that affect your heart rate the heart rate can speed up or slow down because of stress, exercise, medication, trauma or illness even breathing can cause slight fluctuations in heart rate. Factors that affect the rate of dissolving 1 for most solid solutes, the rate of dissolving is greater at a higher temperature - at high temperatures, the solvent molecules have greater kinetic energy, thus collide more frequently.
Effect of pressure on rate of chemical reactions a change in the pressure will only affect the rate of reaction for chemical reactions involving gaseous reactants an increase in the pressure will lead to an increase in the rate of reaction. The changes the fed makes to the discount rate filter through the rest of the economy and affect everything from the rate you pay on your mortgage to the interest you earn on your cd and savings account. Factors that affect the rate of reaction of peroxidase purpose: to determine the effect of various factors on the rate of reaction between an enzyme and its substrate, and also to determine the optimal ranges under which the enzyme activity is maximized. The factors that affect the rate of a reaction are: 1) the temperature of the reaction the higher the temperature the faster particles move particles moving faster means more collisions the collisions are also happening at a higher energy so will have a greater chance of being successful 2) the.
The rate of gastric emptying markedly influences the rate at which drugs are absorbed, whether they are acids, bases, or neutral substances in general, factors that accelerate gastric emptying time, thus permitting drugs to reach the large absorptive surface of the small intestine sooner, will increase drug absorption unless the drug is slow. Factors affecting the required rate include interest rates, risk, market returns and the overall economy interest rates changes in short-term interest rates, usually because of us federal reserve action, lead to changes in other short-term and long-term rates, including us treasury bill rates. Rate of diffusion is influenced by several factors including temperature, concentration difference and particle size the diffusion rate is also affected when there is a change in distance between the points where diffusion occurs diffusion is the movement of atoms or particles from an area of high. The rates at which reactants are consumed and products are formed during chemical reactions vary greatly we can identify five factors that affect the rates of chemical reactions: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the. The brain is the primary controller of respiratory rate it receives input from sensors that detect oxygen and carbon dioxide levels in the blood blood ph -- a reflection of its relative acidity or alkalinity -- also influences respiratory rate activity level and the presence of drugs or alcohol.
Factors affecting response rates in survey development there is an extensive literature on design and development web surveys, primarily focusing on two major factors influencing the response rate, content of web questionnaires and presentation of web questionnaires. Factors affecting corrosion rate taking corrosion into account when designing hvac for vessels - by jeroen fijan, 6 june 2016 there are many factors that influence the corrosion of metal. Basically the higher the temperature the higher the rate of evaporation (factors affecting the rate of evaporation) this is the most notable factor that affects rates of evaporation the way we will test this is by having two bowls of water. The factors that affect reaction rates are: surface area of a solid reactant concentration or pressure of a reactant temperature nature of the reactants presence/absence of a catalyst a change in one or more of these factors may alter the rate of a reaction in this lesson, you will define these factors, and describe and predict their.
In general, alcohol is metabolized at a different rate in women than it is in men this is due to general differences in body composition studies have also shown that women have fewer of the enzymes used to metabolize alcohol than men do (alcohol dehydrogenase and acetaldehyde dehydrogenase. Temperature increases the kinetic energy of the molecule so it moves faster and hence the rate of diffusion increases the more the concentration gradient the higher the driving force of the process and hence the higher the rate of diffusion. Summary of factors that affect chemical reaction rate the chart below is a summary of the main factors that influence reaction rate keep in mind, there is typically a maximum effect, after which changing a factor will have no effect or will slow a reaction.
Factors affecting solubility: the solubility of a substance depends on the physical and chemical properties of that substance in addition to this, there are few conditions which can manipulate it. 10 factors that affect your pulse & heart rate by: emily lockhart on wednesday, may 29th view all on one page (2 of 10) tweet pin it 2 emotional stress i’m sure when the stress gets heavy you’ve noticed that your body naturally responds with a quickening pulse the same goes for fear, another type of anxiety, which prompts the flight.
Breathing is a necessary function for human beings it supplies oxygen for a process called cellular respiration, which is how cells manufacture the energy they need for their life functions. To understand the factors that affect reaction rates what is the relationship between each of the following factors and the reaction rate: reactant concentration, temperature of the reaction, physical properties of the reactants, physical and chemical properties of the solvent, and the presence of a catalyst. Several factors that affect the rate of diffusion include temperature, density of the diffusing substance, medium of diffusion and concentration gradient temperature as temperature increases the average kinetic energy of particles increases greater kinetic energies lead to increased velocities the increased velocity means that there is a.
