The numerical valuse of `P_(c),V_(c),T_(c)` are
`(a)/(27b^(2)),3b,(8a)/(27Rb)` respectively
The compressibility factor Z at critical condintions is `(3)/(8)` .

Text Solution

Verified by Experts

`(RT_(c))/(P_(c)V_(c))=(R xx 8a xx 27b^(2))/(27Rbxxaxx3b)=(8)/(3)` .

Assertion: The numerical values of P_(c ), V_(c ) and T_(c ) are (a)/(27b^(2)), 3b and (8 a)/(27 Rb) respectively. Reason: The compressibility factor Z at critical conditions is 3//8

The value of compressibility factor at the critical state the gas matches with the Z_(c ) is

The essential conditions for liquefaction of gases were discovered by Andrews in 1869 as a result of his study of pressure-volume-temperature relationship for CO_(2) . If was found that above a certain temperature, it was impossible to liquefy a gas whatever the pressure was applied. The temperature below which the gas can be liquefied by the application of pressure alone is called critical temperature (T_(c)) . The pressure required to liquefy a gas at this temperature is called the critical pressure (P_(c)) . The volume occupied by one mole of the substance at the critical temperature and pressure is called critcal volume. Critical constants are related with van der Waals' constant as follows: V_(c) = 3b, P_(c) = (a)/(27b^(2)), T_(c) = (8a)/(27 Rb) The pressure required to liquefy a gas at the critical temperature is called :
