Assertion (A) : The value of K increases with increase in temperature in case of endothermic reaction
Reason (R) : The increase in temperature shifts the equilibrium in the backward direction in case of exothermic reaction.

A

If both (A) and (R) are correct, and (R) is the correct explanation for (A)

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A)

C

If (A) is correct, but (R) is incorrect

D

If (A) is incorrect, but (R) is correct.

Text Solution

Verified by Experts

The correct Answer is:
D
In endothermic reaction, on increasing the temperature, reaction shifts to forward direction.
