Do you understand the relation between ∆E and ∆H and why work (w) is important to this? (23) - Correct Answers∆H = ∆E + P×∆V, where ∆E is the internal energy change and ∆H is the enthalpy change. If P and ∆V are constant, then we can say that ∆H is equal to ∆E. Work is equal to -P×∆V. ∆E = q - P×∆V which is also ∆E = q + w. ∆H = q + w + P×∆V. We can rewrite our first equation as ∆H = ∆E - w. So if work is constant, then again ∆H = ∆E. ...
