Question

This question also asks for plots - please remember to include them!

Final volume isn't given, just leave it in the formula as vf.

Calculate the work done during 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 final expression. Plot on the same graph the indicator diagrams for the isothermal reversible expansion of (a) a perfect gas, (b) a van der Waals gas in which a 0 and b 5.11 x 10-2 dm3 mol, and (c) a 4.2 dm6 atm mol2 and b 0. The values selected exaggerate the imperfections but give rise to significant effects on the indicator diagrams. Take V-1.0 dm3, n-1.0 mol, and T-298 K
