Question

For a system in equilibrium, $\Delta G=0$, under conditions of constant ________.

• A. temperature and pressure
• B. temperature and volume
• C. pressure and volume
• D. energy and volume

Answer 1

The correct option is A temperature and pressure

For a system in equilibrium, $\Delta G=0$, under conditions of constant temperature and pressure.
$\Delta G=\Delta G^o+RTlnK$

When, $\Delta G=0$,

$\Delta G^o=-RTlnK$
