Correct answer

B. Given below are two statements. Statement I: The choice of reducing agents for metals extraction can be made by using

Step-by-step solution

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.

The correct reaction profile diagram for a positive catalyst reaction.

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
