Vedclass · Answer

(B) The Arrhenius equation is given by $K = Ae^{-\frac{E_a}{RT}}$.Statement $(A)$ is incorrect because a high activation energy $(E_a)$ implies a slow reaction,not a fast one.Statement $(B)$ is correct because as temperature $(T)$ increases,the fraction of molecules with energy greater than $E_a$ increases,leading to more effective collisions.Statement $(C)$ is correct because the term $e^{-\frac{E_a}{RT}}$ shows that the sensitivity of $K$ to temperature changes increases as $E_a$ increases.Statement $(D)$ is correct because the pre-exponential factor $(A)$ represents the frequency of collisions,which is independent of the energy threshold.Therefore,the correct statements are $(B)$,$(C)$,and $(D)$.
