The effect of temperature on the reaction rate and reaction yield of the reaction between hydrochloric acid HCl and magnesium ribbon Mg can be explained using the collision theory and Le Chatelier's principle.Reaction: Mg s + 2HCl aq MgCl2 aq + H2 g 1. Effect on reaction rate:According to the collision theory, the rate of a chemical reaction depends on the frequency of collisions between the reacting particles and the energy with which they collide. As the temperature increases, the kinetic energy of the particles also increases. This leads to more frequent collisions and a higher proportion of collisions with sufficient energy to overcome the activation energy barrier.In the case of the reaction between hydrochloric acid and magnesium ribbon, an increase in temperature will increase the reaction rate. The HCl molecules and Mg atoms will collide more frequently and with greater energy, resulting in a faster production of magnesium chloride MgCl2 and hydrogen gas H2 .2. Effect on reaction yield:Le Chatelier's principle states that if a system at equilibrium is subjected to a change in temperature, pressure, or concentration of reactants or products, the system will adjust itself to counteract the change and restore a new equilibrium.For the reaction between hydrochloric acid and magnesium ribbon, the reaction is not reversible under normal conditions, as the hydrogen gas produced escapes from the system. Therefore, Le Chatelier's principle does not directly apply to this reaction in terms of reaction yield.However, it is important to note that increasing the temperature may lead to side reactions or decomposition of reactants or products, which could indirectly affect the reaction yield. In this specific reaction, the effect of temperature on reaction yield is likely minimal, as both reactants and products are relatively stable under moderate temperature changes.In summary, increasing the temperature will increase the reaction rate between hydrochloric acid and magnesium ribbon, while the effect on reaction yield is likely minimal.
