1. A gas mixture entering a reactor has the following compounds with respective flow rates: methane ( 1200 kmol/h); ethane (30 kmol/h), n-propane (5 kmol/h), n-butane (3 kmol/h), CO2 (150 kmol/h) and H2O (200 kmol/h). The temperature of the gas stream in 500 K. You need to compute the Z-factor in a pressure range of 1-20 atm and plot Z vs P using: i. ideal gas law ii. Peng-Robinson equation of state a) Write the algorithm and pseudocode to solve the problems. (8 Marks) b) Write MATLAB code to compute the Z-factor, test the program and present the results.
