The rate at which a reaction occurs is governed by a variety of factors these include the concentration of the the aim of this experiment is to investigate the affect of a change in concentration on the rate of reaction the aim of this experiment was to determine experimentally the affect on the rate of reaction of a change in. 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. We controlled the amount of hydrogen peroxide and the amount of each catalysts to make sure that the change of compounds are the only factor that affect the rate of decomposition the independent variable is the different types of catalysts, the dependent variable is the rate of decomposition.

In this lesson we go through the five factors that affect the rate of a reaction: state of division of a solid (surface area), concentration, pressure of a gas, temperature and catalysts. Factors affecting the rate of photosynthesis: the main factors affecting the rate of photosynthesis are light intensity, temperature and carbon dioxide concentration as light intensity increases, the photosynthetic rate increases until a point is reached where the rate begins to level off.

The temperature had to be controlled because as this paper written by susanne schwerin et al in 2009 shows that temperature has a positive correlation to the heart rate of daphnia 1 size of daphnia - in this experiment the effects of individual differences between the daphnia are unavoidable, however we can control for them as possible for. Core practical 9: investigate factors affecting the rate of aerobic respiration using a respirometer objectives to understand how to use a respirometer to be able to interpret and evaluate respirometer data safety soda lime is corrosive wear eye protection, do not touch the soda lime use a spatula to position it in the respirometer and do.

10 factors affecting the rate of a chemical reaction what you will accomplish in this experiment you’ll investigate two of the four factors that affect the rate of a chemical reaction specifically, you’ll study the impact of. Factors that affect enzyme action investigating the effects of factors on enzyme activity gives opportunities for planning and carrying out experiments under controlled conditions a) investigate and explain the effects of the following factors on the rate of enzyme-catalysed reactions. Learning objectives: 1) to design and conduct an experiment to explore factors that affect photosynthesis 2) to connect and apply concepts, including the relationship between cell structure and function, strategies for capture and stores of energy, and the diffusion of gases across membranes. Many factors affect the activity of enzymes and it is very easy to investigate become denatured, or not work at all other factors such as concentration of enzymes and substrates affect the rate of reaction all these factors will be investigated in this topic guide • carry out suitable experiments investigating temperature change.

Experiment to investigate factors affecting the rate

The aim of this experiment is to investigate whether changing the concentration of a solution will have any effect on the rate of the reaction we are trying to prove that increasing the concentration will speed up the rate of the reaction. Working in groups of 4, you will design and carry out 4 experiments to qualitatively investigate 4 factors that affect reaction rate: temperature, concentration, surface area, and a catalyst. Investigating the factors affecting enzymes experimentally versus one of the determinants affecting the reaction rate – these may be temperature, enzyme concentration, substrate concentration, or ph – and you will have to perform an experiment to manually calculate this relationship how science works. Factors that affect the rate of reactions factors that affect rate there are four main factors that can affect the reaction rate of a chemical reaction: 1 reactant concentration increasing the concentration of one or more reactants will often increase the rate of reaction this occurs because a higher concentration of a reactant will.

This activity is an investigation regarding evaporation and the factors that affect it in this inquiry or guided inquiry (depending on grade level) investigation, students will examine conditions to see what affect these conditions have on evaporation rates. Labbench activity design of the experiment the potometer a potometer is a device that measures the rate at which a plant draws up water since the plant draws up water as it loses it by transpiration, you are able to measure the rate of transpiration. Mashrek international school investigate the factors that affect the rate of respiration in yeast (temperature) fawzi el ansari biology hl title: investigate the factors that affect the rate of respiration in yeast (temperature) aim: the aim of this experiment is to investigate the effect of changing the temperature on the rate of respiration in yeast.

Four factors which affect rates of reaction: we will be investigating the rates of reaction when we will mix together sodium thiosulphate trial run 1 – how concentration of sodium thiosulphate affects rate in this experiment we did a trial run to familiarise ourselves with the experiment and the. Investigate the affect of temperature on the rate of reaction you may use any of the materials listed above in your investigation keep in mind that, in any experiment where you want to determine the affect of one variable, you should attempt to keep all other variables constant. Investigating factors affecting the rate of photosynthesis class practical in this experiment the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of elodea or cabomba.
