Question

For the reaction $A + B ightarrow C$, adding a catalyst decreases the activation energy by $20 	ext{ kJ/mol}$. How does this impact the overall enthalpy ($\Delta H$) of the reaction?

Prashant Kotian · Accepted Answer

Correct answer: D. A positive catalyst provides an alternative pathway with a lower energy barrier () but does not alter the absolute potential energies of the reactants or products, thus remains constant.
