Critical constants of a gas with van der Waals parametersEstimate the critical constants of a gas with van der Waals parametersa= 1.32 atm L^2/mol^2b = 0.0436 L/mol
I believe the critical constants are Vm = 3bT = 8a/(27Rb)P = a/(27b^2)
Van der Waals gas
I know to convert 1.32 atm*L^2/mol^2 into something with cm^3 for a, and then plug into each equation.b would be equal to 43 cm^3/mol
