How can I solve thermochemistry changes of state/phase problems?

Nov 20, 2015

When a compound is changing phase, i.e. it is in a phase transition, it is in equilibrium. That means $\Delta {G}_{\text{trs}} = 0$. So:

cancel(DeltaG_"trs") = DeltaH_"trs" - T_"trs"DeltaS_"trs"

$\textcolor{b l u e}{\Delta {H}_{\text{trs" = T_"trs"DeltaS_"trs}}}$
