In situations where the ideal gas law does not apply a real gas law needs to be used. One such real gas law is the Van der Waals equation (given below). The constants "a" and "b" are species specific (P + a/V^2) (V - b) = RT where: P = pressure in atm a = 9.24 (atm l^2)/mol^2 (for propane) b = 0.0907 l/mol (for propane) V = specific volume in l/mol R = universal gas constant (l atm)/(mol K) T = 450 K The following data were collected for propane using an experimental piston apparatus. Use EXCEL to calculate the pressure predicted by the Van der Waals equation, then create a plot that shows the data along with the predicted pressures.
