Increasing the temperature generally increases the reaction rate of a chemical reaction, including the reaction between hydrogen peroxide H2O2 and potassium iodide KI . This is because higher temperatures provide the reactant molecules with more kinetic energy, causing them to move faster and collide more frequently with greater force. These more frequent and energetic collisions increase the likelihood of successful reactions, leading to a higher reaction rate.In the case of the reaction between hydrogen peroxide and potassium iodide, the reaction can be catalyzed by iodide ions I- and proceeds as follows:H2O2 aq + 2 I- aq 2 H2O l + I2 aq When the temperature is increased, the reaction rate increases due to the reasons mentioned above. However, it is important to note that extremely high temperatures may cause the hydrogen peroxide to decompose more rapidly, which could affect the overall reaction rate. Additionally, the reaction rate may be influenced by other factors such as the concentration of the reactants and the presence of catalysts.
