Vedclass · Answer

(B) The correct answer is $B$.
By definition,the standard enthalpy of formation $(\Delta_fH^\circ)$ and standard Gibbs free energy of formation $(\Delta_fG^\circ)$ of an element in its most stable state at $298 \ K$ and $1 \ bar$ pressure is zero.
However,the absolute entropy $(S^\circ)$ of a substance at standard state is not zero,as per the $3^{rd}$ law of thermodynamics,which states that the entropy of a perfect crystal is zero only at $0 \ K$.

Which of the following state functions is not zero at the standard state?
