(1) Vapor pressures of methanol over the range between its triple point and critical point are represented by: In psat(bars) = 20.44 - 5466.9/T - .01661 T +1.187 x 10-5 T2 where T is in K. The second virial coefficient and saturated liquid volume of methanol at 450 K are -370 cm3/mol and 53.6 cm3/mol respectively. Estimate: (a) the fugacity of methanol at 450 K and 15 bars (b) the fugacity of methanol at 450 K and 45 bars (C) the latent heat of vaporization of methanol at 450 K from the Clausius-Clapeyron equation. (d) the latent heat of vaporization of methanol at 450 K from the Clapeyron equation
