(i) possible at high temperature

(ii) possible only at low temperature

(iii) not possible at any temperature

(iv) possible at any temperature

Solution :-

Right answer is (iv) possible at any temperature

\( \Delta G\) should be –ve, for spontaneous reaction to occur

\( \Delta G = \Delta H – T\Delta S \)

As per given in question,

\( \Delta H\) is –ve ( as heat is evolved)

\( \Delta S\) is +ve

Therefore, \( \Delta G\) is negative

So, the reaction will be possible at any temperature.
