320231 In the equilibrium \({\text{P + Q}} \rightleftharpoons {\text{R + S}}\), the activation energy for forward reaction is \({\rm{15}}{\mkern 1mu} \,{\rm{k}}{\mkern 1mu} \,{\rm{cal/mole}}\) and that of backward reaction is \({\rm{25}}\,{\rm{k}}\,{\rm{cal/mole}}\). Which one of the following statement is correct?

320232 Assertion :
If the activation energy of a reaction is zero, temperature will have no effect on the rate constant.
Reason :
Lower the activation energy, faster is the reaction.
