Assertion (A): The endothermic reactions are favoured at lower temperature and the exothermic reactions are favoured at higher temperature.
Reason (R ) : when a system in equilibrium is disturbed by changing the temperature, it will tend to adjust itself so as to overcome the effect of the change.

A

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

B

both (A) and (R ) are correct, but(R ) is not a correct explanation for (A).

C

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

D

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