For sulfur dioxide, Tcr=430.7 K and Pcr=77. Calculate:

For sulfur dioxide, Tcr=430.7 K and Pcr=77.8 am. Calculate:a) the critical van der Waals constants for the gasb) the critical volume of van der Waals SO2c) the pressure exerted by 1 mole of SO2 occupying a volume of 500 cm^3 at 500 K. Compare this with the pressure which would be exerted by an ideal gas occupying the same molar volume at the same temperature.
