MCQ
For an exothermic reaction, delta H = -100 kJ and forward activation energy = 60 kJ. The activation energy of the reverse reaction is:
Unit-8 Energetics
A 40 kJ
B 160 kJ
C 100 kJ
D 60 kJ
Explanation

The reverse activation energy equals the forward activation energy plus the magnitude of delta H, i.e., 60 + 100 = 160 kJ.
