Which mechanism explains increased reaction rate by a catalyst in chemical reactor at constant temperature?

A)Lowering activation energy of transition state
B)Increasing average kinetic energy molecules
C)Raising reactor pressure above equilibrium
D)Enhancing reactant concentration proximity

💡 Explanation

When a catalyst binds reactants, it provides an alternative lower-energy pathway due a stabilized transition state, thus lowering the activation energy according to Arrhenius equation. Therefore a faster reaction rate emerges, rather than kinetic energy increase (temperature change), pressure shifts or reactant concentration modifications.
