Q. If an endothermic reaction occurs spontaneously at constant temperature $T$ and $P$ , then which of the following is true ?

Solution:

For endothermic reaction $\Delta H$ is positive ie, $\Delta H > 0$.
For a spontaneous process $\Delta G $ is always Negative and $\Delta G = \Delta H - T\Delta S =$ thus, to maintain the value of $\Delta G$ negative, $\Delta S$ must be positive ie, $\Delta S > 0$.
