Irreversible Entropy Changes

Postby mcredi » Tue Feb 12, 2019 7:52 pm

When talking about entropy change due to temperature change when the process was done irreversibly, why do we use deltaS = nRln(t/t)

Because ∆S = qrev/T, if you’re looking for change in entropy due to temperature change, you can substitute out q for nC∆T, then simplify to get ∆S = nCln(T2/T1).
