Question

A protein in denatured state (D) is in equilibrium with native state (N). At 360 K, both N and D states are equally populated. If the standard entropy change for the reaction at this temperature Δ ⁰ = -139 J K ⁻¹ mol ⁻¹ , then the corresponding standard enthalpy change ΔH ᴼ for the reaction in kJ mol ⁻¹ (rounded off to one decimal place) is
