The activation energy of a reaction is 2...

The activation energy of a reaction is 24.0 kcal `mol^(-1)` at `27^(@)C` and the presence of catalyst changes its activation energy to one-fourth at the same temperature. The approximate ratio of rate in the presence of catalyst to rate in the absence of catalyst will be (use R = 2 cal `mol^(-1) K^(-1)` ).
