WebJan 30, 2024 · In chemical reactions involving the changes in thermodynamic quantities, a variation on this equation is often encountered: ΔGchange in free energy = ΔHchange in enthalpy − TΔS(temperature) change in entropy. Example 1.1. Calculate ∆G at 290 K for the following reaction: 2NO(g) + O 2(g) → 2NO 2(g) Given. ∆H = -120 kJ. WebThe enthalpy was defined by: H =U + pV by differential: dH = dU + pdV +Vdp The natural variables of H are S and p represented as H(S,p) and dU =TdS − pdV ∴dH =TdS − pdV + …
