Temperature plays a significant role in the rate of reaction between sodium thiosulfate Na2S2O3 and hydrochloric acid HCl . The reaction between these two chemicals can be represented by the following balanced equation:Na2S2O3 aq + 2HCl aq 2NaCl aq + H2O l + SO2 g + S s As the temperature increases, the rate of reaction between sodium thiosulfate and hydrochloric acid also increases. This is because, at higher temperatures, the kinetic energy of the particles increases, causing them to move faster and collide more frequently with greater energy. These more frequent and energetic collisions increase the likelihood of successful collisions, where the reactant particles have enough energy to overcome the activation energy barrier and form products.According to the Collision Theory, the rate of a chemical reaction depends on the frequency of successful collisions between reactant particles. The Arrhenius equation further explains the temperature dependence of reaction rates, stating that the rate constant k of a reaction is related to temperature T by the following equation:k = Ae^-Ea/RT where A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin.In summary, as the temperature increases, the rate of reaction between sodium thiosulfate and hydrochloric acid increases due to more frequent and energetic collisions between reactant particles, resulting in a higher probability of successful collisions and product formation.
