Assume that O2(g) and H20(g) can be described by the van der Waals equation of state. Decide which between 1 mole of O2 and H20 has the highest pressure at the same value of T and V. Use the following van der Waals parameters: 02(g): a = 1.382 dm^6 bar mol^-2,b= 0.0319 dm^3 mol^-1 H2O(g): a= 5.537 dm^6 bar mol^-2, b= 0.0305 dm^3 mol^-1.
