Question

In an exothermic reaction if Δ H is the enthalpy then activation energy is (A) more than Δ H (B) less than Δ H (C) equal to Δ H (D) none of the above

Tardigrade Admin · Accepted Answer

The activation energy depends upon the nature of chemical bonds undergoing rupture during chemical reaction and is independent of enthalpies of reactants and products.
