Question

The correct statement for an exergonic gaseous reaction $A+B⟶3C$ will be:

• A. $\Delta H>0,\Delta S<0$
• B. $\Delta H=0,\Delta S<0$
• C. $\Delta H>0,\Delta S>0$
• D. All of these

Answer 1

The correct option is C $\Delta H>0,\Delta S>0$

An exergonicic reaciton is one where $\Delta G<0$.
Among the given options, the only case where this happens is when:
$\Delta H>0$ and $\Delta S>0$
