Question
The potential energy diagram for a reaction R → P is give below
ᐃHo of the reaction corresponds to the energy :
ᐃHo of the reaction corresponds to the energy :
Options
A.a
B.b
C.c
D.a + b
Solution
Activation energy of forward reaction = a
Activation energy of backward reaction = a
∴ ᐃH = b - a
Since b > a, there fore reaction is exothermic
Activation energy of backward reaction = a
∴ ᐃH = b - a
Since b > a, there fore reaction is exothermic
