    Hey, I'm having a bit of a mental block on the last part [part (f)] of the attached question. It asks to make use of the kinetic and potential [lennard-jones?] energies but I'm not sure how to go about that. Any hints on how to proceed?

    I've not, although I have a sneaking suspicion it's relatively straightforward.

    what did you get for part e?
    If I recall correctly the critical temperature of the gas is defined as the temperature when the derivatives in part (e) are both equal to zero.
    You should then have a pair of simultaneous equations which you can solve for T, but I'm afraid I don't see how to involve the kinetic energy, it's been a while.

    Thanks for the reply. Yeah, it's how to factor in the kinetic energy that I'm not sure about. And even the potential. For (e) I just differentiated, and double differentiated, pv=nrt, but when I set them to zero and simultaneously solve them for T, I just end up with T=0 which is no help.
