Question

An exothermic process, non-spontaneous at high temperature, will become spontaneous at low temperature.

• A. True
• B. False

Answer 1

The correct option is A True

Reaction is exothermic,
so $\Delta H=-ve$
and as $\Delta G=\Delta H-T\Delta S>0$ at high temperature and reaction will be spontaneous at low temperature as
$\Delta G=\Delta H-T\Delta S<0$
