The addition of a positive catalyst increases the rate of a chemical reaction. This occurs because t — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

A positive catalyst provides an alternative reaction pathway that requires a lower activation energy ($E_a$). By lowering the energy barrier, more reactant molecules possess sufficient energy to reach the transition state, thereby increasing the rate of the reaction. It does not alter the overall enthalpy ($\Delta H$) of the reaction.
