5 moles of air are allowed to expand isothermally at T = 300 K from 20 L to 50 L. If air obeys the van der Waals equation of state, calculate the entropy change associated with such expansion. The van der Waal EOS is given by: RT P = a V — Ь V2 where V is the molar volume of the gas. The van der Waals constants can be calculated using: Ve = 3b 8a Te 27RB where Ve and Te are the critical constants which can be obtained from Perry's Chemical Engineering Handbook.

5 moles of air are allowed to expand isothermally at T = 300 K from 20 L to 50 L. If air obeys the van der Waals equation of state, calculate the entropy change associated with such expansion. The van der Waal EOS is given by: RT P = V - b a V2 where V is the molar volume of the gas. The van der Waals constants can be calculated using: Ve = 3b 8a Te 27RB where Ve and Te are the critical constants which can be obtained from Perry's Chemical Engineering Handbook.
