Question 1 Report

Magnesium (IV) oxide is known to hasten the decomposition of hydrogen peroxide. Its main action is to?
Answer Details
Magnesium (IV) oxide works as a catalyst in the decomposition of hydrogen peroxide, which means it helps speed up the reaction without getting used up in the process. The main action of the catalyst is to lower the activation energy for the reaction, making it easier for the reactants to overcome the energy barrier and react with each other. This makes the reaction occur more quickly than it would without the catalyst. Therefore, the correct option is: "lower the activation energy for the reaction".
