Homework Help: Berthelot equation of state - virial coefficient and taylor series

  1. Oct 2, 2009 #1
    Using the taylor series result

    Vm / Vm - b = 1 + b / Vm + ...

    and the definition of hte compressibility factor Z = PVm / RT, derive an expression for the first virial coefficient in terms of a and b for the Berthelot equation of state.

    Hi sunkissed23, welcome to PF!:smile:

    As per forum rules (Which you agreed to when you signed up for your account!:wink: ), you need to make some attempt at the solution and/or explain where you are stuck. If you haven't done so already, I'd look up "Virial coefficients" in your text...
