Question

An exothermic reaction is always spontaneous.

If true enter 1, else enter 0.

Answer 1

For a reaction to be spontaneous, $\Delta G<0$

$\Delta G=\Delta H-T\Delta S$

Even when reaction is exothermic i.e., $\Delta H<0,\Delta G$ can be +ve when $T\Delta S<\Delta H$.

Hence, the statement given is incorrect.
