A2 Planning: The determination of a rate equation Ladoki Toya Aim The purpose of this experiment is to develop a method to determine the rate equation for the reaction between Magnesium ribbon and 2.0mol dm Hydrochloric acid, HCl. Hypothesis and Theory When I react the magnesium ribbon with hydrochloric acid they will undergo the reaction according to the equation below: Mg(s) + 2HCl(aq) --> MgCl (aq) + H (g) For a reaction to be successful the molecules must collide with sufficient kinetic energy in order to surmount the energy barrier, also known as the activation energy. When there is an increased concentration of reactants then there is a greater chance of these successful collisions occurring therefore speeding up the reaction (As How far, How fast?). According to the collision theory, I should expect that as I increase the concentration of hydrochloric acid then the reaction rate would also increase because a higher frequency of collisions will increase the...
