#DeltaH^o - TDeltaS^o = 0# at Equilibrium (i.e., boiling point) and 'T' is the Thermodynamic Boiling Point for the phase transition.

Explanation:

From #DeltaH^o#-#TDeltaS^o# = 0 => Equilibrium Conditions

=> #DeltaH^o = TDeltaS^o# => #T = (DeltaH^o"/"DeltaS^o")#

#DeltaH^o = sumn*DeltaH^o(Products) - sumn*DeltaH^o(Reactants)#

#DeltaS^o = sumn*S^o(Products) - sumn*"S^o(Reactants)#

Example:
Determine the Thermodynamic Boiling Point of Water.
