A protein undergoes reversible thermal denaturation from its initial state N to denatured state D according to $N \rightleftharpoons D$. At $60^{\circ}C$, the concentrations of both N and D are equal at equilibrium, and the standard enthalpy change of denaturation is $666~kJ~mol^{-1}$. The standard entropy change ($\Delta S^{\circ}$ in $kJ~K^{-1}~mol^{-1}$) of the protein upon denaturation at $60^{\circ}C$ is closest to
