##### Partial Molar Enthalpy

##### Description

The molar enthalpy of a binary mixture of A and B is plotted as a function of the mole fraction of component A. The end points of the molar enthalpy are the pure-component enthalpies (H

_{A}and H_{B}). The partial molar enthalpies \(\overline{H}_A\) and \(\overline{H}_B\), are obtained by drawing a tangent line at the black point (indicating the mole fraction of the solution). The intersections of this tangent with the y axis at x_{A}= 0 and x_{A}= 1 correspond to \(\overline{H}_B\) and \(\overline{H}_A\), respectively. Change the mole fraction of A in the mixture with the slider. For an ideal solution (non-ideal parameter = 0), the enthalpy of the mixture is a linear function of the molar enthalpies of the pure components. For a non-ideal solution, a parameter that represents the deviation from ideality can be varied. view simulation and instructional video
