Explain the effect of catalyst on the activation energy of the reaction with the graph.

Text Solution

Verified by Experts


Catalyst provides an alternate pathway by reducing the activation energy and lowering the energy barrier. More molecules enters the threshold energy state leading to chemical reaction and hence increases the rate.
