Reactions that don't take long to make a product have a high rate of reaction, and reactions that take a longer time have a low rate of reaction collision theory different reactions can happen at different rates. Rates of reactions between hcl and magnesium ribbon aim i plan to investigate the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. A chemical reaction occurs when the molecules of the reactants collide with one another in the reacting environment the rate at which a reaction occurs depends on the rate of the collision of the molecules, and the collision rate depends on various factors, which can be altered to change the rate of a reaction.
