The effect of temperature on the rate of reaction of the enzyme catalase using immobilised yeast cells. Prediction Collision theory The collision theory states that when the temperature is increased the particles all move quicker. If they are moving quicker, they're going to have more collisions. Faster collisions increase the rate of reaction. Higher temperatures increase the energy of the collisions, because it makes the particles move faster. Reactions only happen if the particles collide with enough energy. At a higher temperature there will be more particles colliding with enough energy to make the reaction happen. The initial energy is known as the activation energy, and it is needed to break the Initial bonds. I predict that beyond the optimum temperature of the enzyme the reaction rate will decrease. I predict the optimum temperature to be around 40? C. At temperatures above and below the optimum range, the reaction rate will be slower. At lower...
