At high pressures, Ne behaves as an imperfect gas. In the range 300 K to 500 K the equation of state for one mole of Ne (g) can be written as :PV = RT + BP where B is a constant.
(a) Obtain an expression for (∂P/∂T)v for Ne in this temperature range.(b) Use a Maxwell relation to find an expression for ΔS in terms of an initial volume,Vi, a final volume, Vf, and B.
