Vanderwaal's constants for hydrogen chlo...

Vanderwaal's constants for hydrogen chloride gas are a = 3.67 atm `lit^(-2)` and b = 40.8 ml `mol^(-1)`. Find the critical temperature and critical pressure of the gas.

Text Solution

Verified by Experts

`T_(c) = (8a)/(27 Rb)`
`= (8 xx 3.67 )/(27 xx 0.0821 xx 0.0408) = 324.7` K
`= 51.7^(@) C`
`P_(c) = (a)/(27 b^(2)) = (3.67)/(27 xx (0.0408)^(2)))`
`= 81.6` atm
