Question

The compression factor (compressibility factor) for one mole of a van der Waals’ gas at 0ºC and 100 atm pressure is found to be 0.5 Assuming that the volume of a gas molecule is negligible, calculate the van der Waals’ constant ‘a’.

Answer 1

 In case of negligible molecular volume, b = 0, For 1 mole of gas
