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 correct explanation for statement 1
C. Statement 1 is true, statement 2 is false
D. Statement 1 is false, statement 2 is true

Answer

D

Explanation

The statement is clearly wrong accroding to Le-chateliers principle, which states that, ''Increase in temperature shifts the equilibrium in the forward directon of those reaction which proceed with absorption of heat (endothermic reactions), and in the backward direction of those reactions which proceed with the evolution of heat (exothermic reactions),'' E is clearly true again according to Le-chatelier principle.
