Chemical Kinetics · Catalyst and arrhenius equation

At 27$^\circ$C in presence of a catalyst, activation energy of a reaction is lowered by 10 kJ mol$^{-1}$. The logarithm ratio of $\dfrac{k(\text{catalysed})}{k(\text{uncatalysed})}$ is ….

(Consider that the frequency factor for both the reactions is same)
