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.

Options

A. Statement-1 is true, statement 2 is true, statement 2 is a correct explanation for statement.1
B. statement-1 is true, statement 2 is true, statement 2 is not a correc explanation for statement 1
C. statement 1 is ture, statement 2 is false
D. statement-1 is false, statement-2 is true

Answer

D

Explanation

In this case statemetn-1 is wrong because endothermic reactions are favoured at high temperature and exothermic reacts are facoured at lower temperature in accordance with Le Chatelier's principle. Statement -2 is correct as it is in accordance with Le Chatelier's principle Hence (D) is correct option.
