The correct reaction profile diagram for a positive catalyst reaction. — JEE Mains Chemistry Past Papers Chemistry Question

💡 Solution & Explanation

A catalyst drives the reaction through a low energy path and hence Ea is less. That is, the function of the catalyst is to lower down the activation energy. Ea = Energy of activation in absence of catalyst. E’a = Energy of activation in presence of catalyst. Ea – E’a = lowering of activation energy by catalyst.
