Homework Help: Equation for work of a reversible isothermal compression

  1. Sep 11, 2008 #1
    I need to find the equation for the work of a reversible isothermal compression of 1 mol of a gas in a piston/cylinder assembly if the molar volume of the gas is given by

    V= ((RT)/P) + b where b and R are positive constants.

    Not sure what to do .. please help!

    Start with the general equation for boundary work:

    [tex] W_b = \int_1^2{PdV} [/tex]

    Solve the equation you were given in terms of P and plug it into the equation above and integrate.
