Aim: The aim of this investigation is to investigate how varying surface area affects the rate of reaction (amount of Oxygen produced). The hypothesis being tested is 'an increase in the catalyses surface area causes the rate of Oxygen production to increase (rate of reaction).' In order to test this hypothesis, the substrate Hydrogen Peroxide and enzyme catalase in potato will be used. The substrate concentration will be kept constant whilst, the catalyses surface area will be varied, by changing the surface area of the potatoes. The rate of reaction used can be represented by measuring the volume of oxygen produced in a fixed period of time. Prediction: I predict that an increase in surface area of potato, whilst the hydrogen peroxide concentration is kept constant will result in an increase in the amount of oxygen produced. The scientific reasoning behind the prediction is, as the surface area of...
