Correct answer: 0

Arrhenius equation for the rate constant of a reaction in terms of energy of activation is given by

$K = {Ae}^{- \dfrac{Ea}{RT}}$

${K}_{catalyst} = Ae\dfrac{Ea '}{RT}$

${K}_{uncatalysed} = {Ae}^{- \dfrac{Ea}{RT}}$

$\dfrac{{K}_{catalyst}}{{K}_{Uncatalysed}} = e\dfrac{Ea - {E}_{a}^{'}}{RT} = e\dfrac{10 \times 1000}{8 . 314 \times 300} = {e}^{4}$
