The activation energy for a simple chemical reaction `A rarr B` is `E_

1.	The activation energy for a simple chemical reaction `A rarr B` is `E_(a)` in the forward reaction: The activation of the reverse reactionA. `lt 50 kcal`B. 50 kcalC. `gt 50 kcal`D. Either greater than or less than 50 kcal
Answer» Correct Answer - D The energy of activation for the reverse reaction will decided by the fact where the reversible is exothermic or endothermic. For an exothermic reaction `(Delta_(r)H^(Ɵ)is-ve)` thus `(E_(a))_(f)lt(E_(a))_(b)` and for an endothermic reaction `(Delta_(r)H^(Ɵ)is+ve)` Thus `(E_(a))_(f)gt(E_(a))_(b)` . Thus, the energy of activation of reverse reaction is either grater or less than `50Kcal` .
