For an endothermic reaction, where `Delta H` represents the enthalpy of reaction in `kJ mol^(-1)`, the minimum value for the energy of activation will be

Options

A. less than `Delta H`
B. zero
C. more than `Delta H`
D. equal to `Delta H`

Answer

C

Explanation

Eactivation = (Energy intermediate complex) -(Average energy of reactants)
The energy of intermediate complex generally lies above the energy of products.
