From Arrhenius equation k=A Z e-Ea / R T where, A is = frequency factor Ea = energy of activation e-Ea / R T = Boltzmann factor A decrease in activation energy (Ea) will increase rate constant ( k ) and rate of reaction increase.

From Arrhenius equation $k = A Z e^{- E_{a} / RT}$ where, $A$ is
$=$ frequency factor $E_{a}$
$=$ energy of activation $e^{- E_{a} / RT}$
$=$ Boltzmann factor $A$ decrease in activation energy $(E_{a})$ will
increase rate constant $(k)$ and rate of reaction increase.
