Electrolysis System Work and Real Gas Law

  1. Mar 11, 2015 #1
    Greetings Everyone!

    I read a very good thread regarding how Ideal Gas Law is used to calculate system work for the electrolysis of water:

    W = PΔV = (101.3 x 103 Pa)(1.5 moles)(-22.4 x 10-3 m3/mol)(298K/273K) = -3715 J


    I'm trying to figure out how to calculate the system work using Real Gas Law:

    Any help is greatly appreciated!!!

    Work is still the integral of PdV. Anything in particular you're having trouble handling?

    I'm not sure how to solve for energy.
