Investigation - Rate of Reaction To investigate the factors that affect the rate of reaction between magnesium and hydrochloric acid. Collision theory describes the way temperature, concentration and surface area of the solid reactant affects the rate of reaction, by affecting collisions between particles. Particles react when they collide with sufficient energy. At a higher temperature collisions are more frequent, and they also have more energy, both because particles are moving faster. At a higher concentration collisions are again more frequent, as there are more reactant particles in the liquid. Increased surface area of the solid again increases the frequency of collision between reacting particles, as the liquid reactant has greater contact with the solid one. Rate of reaction can also be increased by adding a catalyst, but there is not one for this reaction. We placed 25 cm3 of Hydrochloric acid in a conical flask. We then added 4 cm...
