Question

The relationship between the free energy change $\left(\Delta G\right)$ and entropy change $\left(\Delta S\right)$ at constant temperature $\left(T\right)$ is

• A. $\Delta G=\Delta H+T\Delta S$
• B. $\Delta H=\Delta G+T\Delta S$
• C. $T\Delta S=\Delta G+\Delta H$
• D. $\Delta G=-\Delta H-T\Delta S$

Answer 1

The correct option is B $\Delta H=\Delta G+T\Delta S$

As we know,
$\Delta G=\Delta H-T\Delta S$
So,
$\Delta H=\Delta G+T\Delta S$
