For a hypothetic reaction `ArarrB`, the activation energies for forward and backward reactions are 19 kJ/mole and 9 kJ/mole respectively. The heat of reaction is

A

28 kJ

B

19 kJ

C

10 kJ

D

9 kJ

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta H = E_(a)` for forward reaction `-E_(a)` for backward reaction = 19-9 = 10 kJ.
