Lower the critical temperature of a gas …………. is its rate of liquefation.

Options

A. There is no relation between critical temperature and rate of liquefaction.
B. Faster
C. Moderate
D. Slower

Answer

D

Explanation

When cooled mixture of two gases having different critical temperature then gas which have more critical temperature will liquified first and earlier because, when cooled mixture, gas liquified first whose value of critical temperature is more in opposite way, ..Gas liquify slow whose value of critical temperature is low...
e.g., Critical temperature of `H_(2)` and He gas is 33.2K and 5.3 K respectively. so when cooled mixture of Hc, `H_(2)` then Hc gas liquified first.
