Consider the following reactions at 300 K

$\mathrm{A}⟶\mathrm{B}$ (uncatalysed reaction)

$\mathrm{A}\stackrel{\text{ catalyst }}{⟶}\mathrm{B}$ (catalyst reaction)

The activation energy is lowered by  $8.814 \mathrm{kJ} {\mathrm{mol}}^{-1}$ for the catalysed reaction. How many times the rate of this catalysed reaction greater than that of uncatalysed reaction? $\left(\text{ Given }{e}^{3.33}=28\right.\text{ ) }$
