Question
Reaction A + B → C + D + 38 Kcal has activation energy 20 Kcal. Activation energy for the reaction C + D → A + B is :-
Options
A.20 Kcal
B.-20 Kcal
C.18 Kcal
D.58 Kcal
Solution
ᐃH = -(Ea)backward + (Ea)forward
-38 = - (Ea)backward + 20
(Ea)backward = + 38 + 20 = 58 Kcal
-38 = - (Ea)backward + 20
(Ea)backward = + 38 + 20 = 58 Kcal
