(a) Determine the fugacity coefficients for nitrogen and methane in N2(1)/CH4(2) mixture at 200 K and 30 bar if the mixture contains 40mol%N2. Experimental virial-coefficient data are as follows: B11=35.2B22=105.0B12=59.8cm3mol1 (b) Using the information from part (a), calculate the compressibility factor Z of this gas mixture. Question 3 (10Marks) Part (a) 10 Marks For the system ethylene(1)/propylene(2) as a gas, estimate f^1,f^2,^1& ^2 at 150C,P=30 bar, and y1=0.35. Part (b) Repeat part (a) using thermoSolver software and compare your results and report the error difference in (\%)
