The potential energy diagram for a reaction `R to P` is given below.

`Delta H^(0)` of the reaction corresponding to the energy.

Options

A. a
B. b
C. c
D. `a+b`

Answer

C

Explanation

Activation energy of forward reaction `=a`
Activation energy of backward reaction `=b`
`therefore` Heat of reaction `=b-a =c (b gta)`
`therefore` Reaction is exothermic
