WebΔ E = δ Q − δ W. If the amount of work done is a volume expansion of a gas in, say a piston cylinder instrument at constant pressure, Δ E = δ Q − p d v. Here p is the constant pressure and d v is the change in (specific) volume. So, when do I take into account. δ W = d ( p v) = p d v + v d p. I am assuming that for cases of boundary ... WebΔH surr = change in surrounding’s enthalpy; ΔH sys = change in system’s enthalpy; Also, for a spontaneous process, the total entropy change is 0, i.e. ΔS total > 0. Therefore, TΔS sys – ΔH sys > 0. ΔH sys – TΔS sys < 0. Using the Gibbs equation, it can be said that, ΔG sys < 0. Thus, we can see that any process is spontaneous when the Gibbs energy change of … Webview the basic thermodynamic relations.
