How does the temperature affect the rate of reaction for magnesium? Aim - My aim is to find out how temperature affects the rate of reaction with magnesium. Prediction - I predict that the higher the temperature of the acid, the quicker the reaction with magnesium will take place; the lower the temperature the slower it will take place. Science - I believe this because, when two chemicals react, their molecules have to collide with each other with sufficient energy for the reaction to take place. This is collision theory. The two molecules will only react if they have enough energy. By heating the mixture, you will raise the energy levels of the molecules involved in the reaction. Increasing temperature means the molecules move faster. This is kinetic theory. So by heating the particles up the magnesium particles will collide harder with the hydrochloric acid, causing it to dissolve faster, whereas if it...
