A catalyst which increases the rate of reaction is a positive catalyst. An example is Manganese(IV)Oxide which speeds up the decomposition of potassium trioxochlorate(V). Therefore, Moderate heat is required because the catalyst MnO2 acts by increasing the rate of reaction.

catalyst increase the rate of chemical reaction and also power the energy barrier take note 👌❤️
The correct answer is C-increasing the rate of the reaction
Because the catalyst, Mno2 lowers the temperature and makes the reaction progress at a faster rate
