"WebSep 16, 2024 · Recognizing that Δ (PV) = Δ (nRT), we can rewrite Equation 5.3.4 as follows: ΔH = ΔU + Δ(PV) = ΔU + Δ(nRT) At constant temperature, Δ (nRT) = RTΔn, where Δn is the difference between the final and initial numbers of moles of gas. Thus ΔU = ΔH − RTΔn For reactions that result in a net production of gas, Δn > 0, so ΔU < ΔH. " - Equation for internal energy
