WebVan der waals constant a is a mixture of inter molecular forces and b is a measure of molecular size. A greater value of a and lesser value of b supports qualification of a given gas. Therefore, chlorine is more easily liquefied than ethane because a for Cl 2> a for C 2H 6 but b for Cl 2> b for C 2H 6. Solve any question of States Of Matter with:- WebFind a relationship for Cp - Cv for a gas for which the van der Waals equation of state P = RT/(v - b) - a/v2 is applicable.

WebSep 25, 2024 · The van der Waals constants, referred to molar volume, of H2O and CO2 are approximately: H 2 O: a = 5.5 × 10 5 Pa m 6 kmole −2 . ... Thus, at the Boyle temperature, even a non-ideal gas obeys Boyle’s law fairly closely. For a van der Waals gas, the critical temperature is 8a/(27Rb), so the Boyle temperature for a van der Waals is a/(Rb). WebThus, the Joule coefficient for a van der Waals gas is negative. This implies that the temperature of the gas always decreases as it undergoes free expansion. Of course, this temperature decrease is a consequence of the work done in overcoming the inter-molecular attractive forces.
