Assertion : E_(a) of the forward reaction is higher than that of backward reaction in a reversible endothermic reaction. Reason : Increasing the tempreature of the substance increases the fraction of molecules which collide with energies greater than E_(a).

1.	Assertion : E_(a) of the forward reaction is higher than that of backward reaction in a reversible endothermic reaction. Reason : Increasing the tempreature of the substance increases the fraction of molecules which collide with energies greater than E_(a).
Answer» If both assertion and reason are TRUE and reason is the correct explanation of assertion. If both assertion and reason are true butreason is not the correct explanation of assertion. If assertion is true but reason is false. If both assertion and reason are false. Solution :Threshold energy of reactants is less than that of products in reversable endothermic reactions hence, `E_(a)` for FORWARD REACTION is more than `E_(a)` for backward reaction
