Explain (each step) and Answer please
One empirical equations of state of a real gas is: van der Waals: P = RT/V_m - b - a/V_m^2 Evaluate (partial differential s/partial differential V)_T, for a van der Waals and a perfect gas. (A Maxwell relation might help!) For an isothermal expansion, for which kind of gas (vdW or perfect gas) will delta S be greatest? Explain your conclusion.
