Question:medium
The molar entropy of which of the following reaction is negative?
The molar entropy of which of the following reaction is negative?
Show Hint
Quick check for \(\Delta S\): Count only gas molecules.
Reactant side: 7.5 gas. Product side: 6 gas.
Fewer gas molecules \(\to\) Less disorder \(\to\) Negative \(\Delta S\).

- 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
