Homework Statement
Consider the liquid-gas coexistence curve. Show that C_{(g)} − C_{(l)} = T(\stackrel{d}{dT} \Delta_{(vap)}S) for T, P along the coexistence curve. Now use the fact that
\Delta(vap)S = \Delta(vap)H/T along the coexistence curve, and the fact that \Delta(vap)H is positive...
Homework Statement
Use the Clausius-Clapeyron equation and \DeltaHsub = \DeltaHfus +\DeltaHvap at the triple point to show that the slope of solid-gas P-T coexistence curve is greater than the slope of the liquid-gas coexistence curve.

Homework Statement
The Gibbs free energy of benzene decreases continuously with temperature (at fixed pressure) and shows three nearly linear segments corresponding to the solid, liquid and gas phases. The magnitude of the slopes increases as one moves from solid to liquid, and liquid to...
Homework Statement
Consider a reversible isothermal expansion of two moles of CO2 from 1 L to 60 L at 298 K. Assume that CO2 obeys an equation of state P = nRT/(V − nb) − n2a/V 2 with b = .04286 L mol−1 and a = 3.658 L2 bar mol−2.
(a) Calculate W.
