Problem 1: Heat of mixing The partial molar enthalpies of the two components of a binary mixture at 25C are given by the two following equations: H1=100(1+0.08x22)H2=80(1+0.1x12) where the enthalpy is in kJ/mol of mixture. a) Calculate the molar enthalpies of the pure components 1 and 2 . b) Calculate the partial molar enthalpies of the two components at infinite dilution. c) Express the excess partial molar enthalpies of the two components as functions of composition and calculate them at infinite dilution. d) Calculate the molar enthalpy of an equimolar solution. e) Calculate the enthalpy change when the two components are mixed at constant temperature and pressure to produce an equimolar solution. f) Is the mixing process endothermic or exothermic
