Understanding Reaction Kinetics with Hydrogen Peroxide

A researcher is studying the reaction kinetics of the decomposition of hydrogen peroxide (H₂O₂) in an aqueous solution. The reaction follows the rate law: rate = k[H₂O₂]. The reaction rate was observed to double when the concentration of hydrogen peroxide was doubled.

The researcher notes that in the presence of a catalyst, the activation energy of the reaction decreased, which resulted in a significant increase in the reaction rate at room temperature. In order to further investigate the influence of temperature on this reaction, the researcher also conducted experiments at various temperatures and measured the corresponding rate constants.
