Aim: To see if concentration and catalyst affect the rate of reaction. Prediction: My prediction that the higher the concentration of the hydrogen peroxide, the faster the rate of reaction will be. This is because the larger number of acid particles in the same volume, increases the chance of the particles colliding and reacting. Faster collisions increase the rate of reaction. If you double the concentration you double the rate of reaction because you have twice the molecules in the same solution. Theory: A catalyst or enzyme is a substance which speeds up a chemical reaction, at the end of the reaction, the catalyst is chemically unchanged. A reactant can not turn into a new product on it's own. It needs enough energy to start the reaction. A catalyst speeds up a reaction because it lowers the activation energy, which is the amount of energy needed for a reaction. As you increase the concentration...
