Effects on a named variable on rate of a catalase catalysed reaction I am investigating how the concentration of hydrogen peroxide affects the rate of a reaction. I can find this out by finding out how much gas is given off when I place a piece of potato in different concentrations of hydrogen peroxide. As I change the input variable (the concentration), I will measure the amount of gas that has been collected in three minutes. I am using a potato chip that is 2cm. in length, 1cm. wide and 1cm. deep and I am going to be adding this into hydrogen peroxide, which will be diluted with varied amounts of water. Enzymes are biological catalysts; they speed up chemical reactions in living things. Enzymes are specific, which is to say that they will only catalyse one particular reaction. One particular enzyme is catalase. This is the fastest enzyme, and is found in most...
