Please create the GRAPHS for both parts a and b please!!

In this HW you will produce PV isotherms at different temperatures using both the ideal gas law, and the van der waals equation of state. a. First make isotherms for the ideal gas at temperatures of T=475K,T= 450K,T=425K, and T=400K. Plot the isotherms with the pressure on the y-axis and the molar volume on the x-axis. Use a different color or lineshape for each isotherm - a legend is also good. Do it on log-lin plots and lin-lin (pressure on the y-axis and molar volume on the x-axis) plots. For both plots display molar volume limits of 01.0103(m3/mol). For the semi-log I would suggest an upper limit of P=1e8Pa, for the linear plot I would suggest an upper limit of P=1 e 7Pa. b. Now make isotherms for a fluid that obeys the van der Waals volumetric equation of state (EOS) with a=1466.2(L/mol)2kPa, and b=0.1226L/mol. These are the van der Waals parameters for n-butane (according to The Google and Wikipedia). I suggest first converting these parameters to SI units before entering in your code/spreadsheet. Again, make plots as above for temperatures of T=475K,T=450K,T=425K, and T=400K
