The effect of temperature on a reaction rate
In this experiment I shall be investigating how temperature affects the rate of reaction
Rates of reaction
The Factors that affect the rate of reaction are temperature, surface area, concentration, catalysts, light and pressure

The Effects that 1%, 4%, and 16% Sodium Chloride (NaCl) Concentration Had on the Rate of Reaction of Catecholase Enzymes in a Potato (Solanum tuberosum).
Enzymes are a key component of a cell. They make chemical reactions happen faster because they lower the activation energy to make t...

To design short experiments to investigate and explain qualitatively using collision theory the relationship between reaction rate and temperature, concentr...
How a faster pulse rate after exercise affects the amount of carbon dioxide in breath and how males and females pulse rates change or don’t after exercise
There is a chemical reaction that takes place in this lab, O2 + C6H12O6 –> H2O + CO2 + ATP. This represents cellular respir...
An investigation in to the rate of reaction
I am going to investigate the rate of reaction. The reaction I will be using is:
Calcium Carbonate + Hydrochloric acid ---- Calcium Chloride + water + carbon dioxide.
CaCO3 + 2HCl ---- CaCl +H2O + CO2

Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)?
reaction rates and concentration (research paper) By katie prestage
what are reaction rates?
The rate of reaction is the speed in which a reaction takes place. This can be measured by the rate in which a reactant is used up, or the rate a product is created. If a reaction has a low rate, it mea...
EFFECT OF CONCENTRATION ON REACTION RATE
The aim of this experiment is to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide: H2O2(aq) + 2H+(aq) + 2I⁻ → 2H2O(l) + I2(aq) The course of this...
Investigating the factors affecting the rate of a chemical reaction.
In my coursework I will be mainly concentrating on the reaction between dilute hydrochloric acid with marble chips (calcium carbonate).
Calcium carbonate (marble chips) + hydrochloric acid ==> calcium chloride +...
Rate of Reaction
My aim for this experiment is to find the rate of reaction of the following chemicals shown below in the equation furthermore I will use different concentrations of Hydrochloric acid. I will time the rates and record them, plotting them onto a graph showing the line of best...
Aim: To try to see if the temperature affects the rate in which Amylase breaks down starch into maltose. In this reaction starch is the substrate and maltose is the product. Amylase is an enzyme, Enzymes, also called catalysts, are in living things and there are thousand of...
Rate of Reaction
To find out how different concentrations change the rate of reaction
In this experiment the collision theory is in use. It means that when the concentrates solutions of hydrochloric acid is use, more particles are found in the same space, which means they are...

How does altering concentration (mol dm-3) of hydrochloric aci...
How does the temperature affect the rate of reaction?
For our experiments, I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction, with the temperature of this being our variable that we changed. Hydrogen p...
