Step-by-step explanation
Most of the chemical reactions have energy barrier. A positive catalyst in a chemical reaction increases the rate of reaction by lowering the energy barrier. It does not alter the energy of reactant as well as product.
In the above graph, the curve in the presence of catalyst is having less activation energy. The enthalpy change is constant after addition of the positive catalyst
