Real gases are modeled by the van der waals equation by considering interatomic attractions and molecular volume as follows where t is the absolute temperature, p is the pressure, vm is the molar volume, r is the gas constant, and a and b are constants specific to each gas. in contrast, the ideal gas equation pv-rt models gas particles as point masses and does not account for interatomic attractions. a) use mathematica to implement the ideal and van der waals equations of state as two-variable functions p(t, vm) for nitrogen gas (a -1.37012. bar. mol2 b 3.87 x102l. mol; r-8.314 x10-2l. bar. k-1.mol) b) use your p(t, vm) functions to generate two plots of pvs. vn in the molar volume range of o.05 l. mol-1 to 1.0l. mol and pressure range of o to 200 bar, at t127 k and t 300 k. add a title to each plot indicating the temperature value. label both axes (including units). include a legend indicating which curve corresponds to which equation of state. each curve must be rendered in a different color.
