    calculating enthalpy of mixture from Peng-Robinson EOS

    I know the equation for calculating the enthalpy of a mixture using Peng-Robinson. However, there is a derivative, d(am(T))/dT, where am(T) = xi*xj*(a(T,i)*a(T,j))^(1/2) a(T) = ac*(1+k*(1-(T/Tc)^(1/2))^2 k = 0.37464+1.54226*om - 0.26992*om^2 that I am having a difficult time...
