An Investigation to show the factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid Introduction: The collision theory says that successful collisions can only take place when there is enough activation energy, which is caused by particles colliding together head on with enough energy to break the existing bonds to form new ones. When a successful collision occurs a reaction will take place. Aim: In this experiment I will be investigating whether temperature and concentration affect the rate of reaction between magnesium strips and hydrochloric acid. Hypothesis: I predict that as the concentration increases, the speed of the reaction will increase therefore the gas will be produced faster. I believe this because most chemical reactions happen faster when the concentration is higher. At higher concentrations molecules are closer together, which makes it easier for them to collide. Because there are more collisions, the reaction rate is greater. Chemical reactions take place by chance....
