According to Trouton's rule for liquids, dividing the change in enthalpy by this quantity will often yield a change in entropy equal to about 88 joules per kelvin per mole.
In Pxy ["P-sub-x-y"] and Txy ["T-sub-x-y"] diagrams for binary mixtures, these quantities mark the intersection of the bubble point and dew point curves. According to Trouton's rule for liquids, dividing the change in enthalpy by this quantity will often yield a change in entropy equal to about 88 joules per kelvin per mole. The change in this quantity for a solution can be calculated by multiplying the molality of the solution, the van't Hoff factor, and a constant termed Kb ["K-sub-B"]. When this point is reached, the vapor pressure is equivalent to the atmospheric pressure. For 10 points, name this temperature at which substances transition from a liquid to a gas phase.
