Ammonia vapor is compressed to 60 bar and 105°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 <= 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 and use a logarithmic scale for the x-axis. 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 60 bar and 105°C (L/mol).

Ammonia vapor is compressed to 60 bar and 105°C. Use the SRK equation of state to determine
the vapor mass density (g/L). For ammonia, T. = 405.5 K, Pc = 111.3 atm, and to = 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
and use a logarithmic scale for the x-axis. 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 60 bar and 105°C (L/mol).
d. Determine the vapor mass density (g/L).
