Q.3. (a) Calculate the fugacity of a pure gas at 500K and 30 bar. (3 points) (b) Suppose pure liquid is in equilibrium with the gas at 500 K, 30 bar. Calculate the liquid fugacity. (c) Calculate the liquid fugacity at 500 K, 60 bar. Use P,Sat-30 bar. Also comment on the effect of pressure on fugacity. For all parts, given: V/ = 25 cm /mol; Zi (between 0 and 30 bar)=1 -0.015P2 1 bar= 105 N/m and R=83.14 cm.bar/mol.K
