For an endothermic reaction, energy of activation is Ea and enthalpy of reaction is H (both of these in kJ/mol). Minimum value of Ea will be
- Aless than H
- Bequal to H
- Cmore than H
- Dequal to zero
View written solutionFree
Correct answer: C
Here,
Ea = activation energy of forward reaction
E’a = activation energy of backward reaction
H = enthalpy of the reaction

From the given diagram it is clear that
Ea = E’a + H
Ea > H
