A 10C temperature increase generally has a significant effect on the rate of a chemical reaction. In the case of the reaction between hydrochloric acid HCl and magnesium Mg , the rate of reaction will increase with the temperature rise.The reaction between HCl and Mg can be represented by the following equation:Mg s + 2HCl aq MgCl2 aq + H2 g According to the collision theory, an increase in temperature leads to an increase in the kinetic energy of the reacting particles. This results in more frequent and energetic collisions between the reactant molecules, which in turn increases the probability of successful collisions that lead to the formation of products.For many reactions, the rate approximately doubles for every 10C increase in temperature, although this is just a rough estimate and the actual increase may vary depending on the specific reaction. In the case of the HCl and Mg reaction, you can expect a significant increase in the rate of reaction due to the 10C temperature increase, leading to faster production of magnesium chloride MgCl2 and hydrogen gas H2 .
