" Can activation energy for reactions be zero? "

In Arrhenius equation Can activation energy E for a reaction be zero?

if activation energy of a reaction is zero

(A) If the activation energy of a reaction is zero, temperature has no effect on the rate constant. (R ) Lower the activation energy, faster is the reaction.

Assertion (A) : If the activation energy of a reaction is zero, temperature will have no effect on the rate constant. Reason (R ): Lower the activation energy, faster is the reaction.

Assertion (A) : If the activation energy of a reaction is zero, temperature will have no effect on the rate constant. Reason (R ): Lower the activation energy, faster is the reaction.

Will the rate constant of the reaction depend upon T if the E_act (activation energy) of the reaction is zero?
