Derive an expression for the isothermal reversible expansion of a van der Waals gas. Account physically for the way in which the coefficients a and b appear in the expression. Using Maple, plot the expression along with that for an ideal gas. For the van der Waals gas, use a case first where a = 0 and b = 5.11 x 10-2 mol-1 and where a = 4.2 L2 atm mol-2 and b = 0. Take Vi = 1.0 L, Vf = 2.0 L, n = 1.0 mol, and T = 298 K.
