Question

Gibb's free energy G, enthalpy H and entropy S are interrelated as in:

• A. $G=H+TS$
• B. $G=H-TS$
• C. $G-TS=H$
• D. $G=S=H$

Answer 1

Answer: (B)

$G=H-TS$

Gibb's free energy G, enthalpy H and entropy S are interrelated as in $G=H-TS$.

Also, change in Gibb's free energy $\Delta$G, change in enthalpy $\Delta$H and change in entropy $\Delta$S are interrelated as in $\Delta G=\Delta H-T\Delta S$.
