Thermodynamics Q

  1. Nov 17, 2011 #1
    Find (∂G/∂Na)T,p,Na'≠a


    G(T, p, x1, x2,...) = Ʃxaπa(T) + RTƩxaln(xap/p0)

    p.s. the sum is over all alpha. π(T) is some function of T:

    so first i multiplied thru by Ntotal (N).. giving extensive G.. then differentiated this wrt Na.

    My problem is how to differentiate the second part, i.e.

    d/dNa = πa(T) + d/dNa(RTƩNaln(NaP/NP0)

    plssssssss help
