MCQ

Which of the following is not correct?

A
$\Delta\text{G}$ is zero for a reversible reactio.
✓
$\Delta\text{G}$ is positive for a spontaneous reactio.
C
$\Delta\text{G}$ is negative for a spontaneous reaction.
D
$\Delta\text{G}$ is positive for a non $-$ spontaneous reaction.

✓

Answer

Correct option: B.

$\Delta\text{G}$ is positive for a spontaneous reactio.

$\Delta\text{G}$ gives a criterion for spontaneity at constant pressure and temperature.

If $\Delta\text{G}$ is negative $(< 0)$. The process is spontaneous.
If $\Delta\text{G}$ is positive $(> 0)$. The process is non-spontaneous.
If $\Delta\text{G}$ is zero then reaction is at equilibrium.
