Q. For an endothermic reaction where, $\mathrm{\Delta}H$ represents the enthalpy of the reaction in kJ/mol, the minimum value for the energy of activation will be
A) Less than$\ \mathrm{\Delta}H$
B) Zero
C) More than$\ \mathrm{\Delta}H$
D) Equal to$\ \mathrm{\Delta}H$
Explanation
(c)
For an endothermic reaction where $\mathrm{\Delta}H$ represents the enthalpy of the reaction, the minimum value for the energy of activation is more than $\mathrm{\Delta}H,\ ie,\ E_{a} > \mathrm{\Delta}H$
