Ammonia vapor is compressed to 50 bar and 110°C. Use the SRK equation of state to determine the vapor mass density (g/L). For ammonia, T. = 405.5 K, P. = 111.3 atm, and c = 0.257. a. Determine Tr, a, b, m, and a. b. Plot the pressure as a function of specific volume over a range of 0.05-5 L/mol. Make sure to properly label the axes. Plot a sufficient number of points to get a smooth curve. You must use Excel to prepare your plot. Axes should be properly labelled, and the plot must have a title. c. Determine the specific volume of ammonia vapor at 50 bar and 110°C (L/mol). d. Determine the vapor mass density (g/L).
