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

Answer

D

Explanation

Potential energy diagram for an endothermic reaction is

Potential energy of the activated complex should be at least just above the potential energy of the products. Thus, minimum value of `E_(a)` is more than `DeltaH` .
