Partial Molar Enthalpy of a Binary System
« on: March 02, 2011, 10:01:19 AM »
I conducted an experiment on partial molar enthalpy determination. What I have are the following:

component A: Ammonium chloride
component B: Water

mole fraction A = Xa
mole fraction B = Xb

molar enthalpy of the solution = Hs

now, I derived the relationship for X and Hs. I plotted mole fraction of component A (abscissa) versus molar enthalpy of solution (ordinate).

so, i have Hs=f(Xa)

I know I have to take the partial derivative of this with respect to the mole fraction of A at constant mole fraction of B to solve for the partial molar enthalpy of A.

QUESTION:
how do i solve for the partial molar enthalpy of component B? do I just take the partial derivative of Hs=f(Xa) with respect to the mole fraction of B at constant mole fraction of A or do i have to plot Xb versus Hs to derive Hs=f(Xb) then differentiate later on?

thank you very much!
