Assertion :E(a) of the forward reaction...

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

A

Statement 1 is True, statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement is True, Statement 2 is False.

D

Statement is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
B
Threshold energy of reactants is less than that of products in reversible endothermic reactions hence. `E_(a)` for forward reaction is more than `E_(a)` for backward reaction.
