Question

Gases possess characteristic critical
temperature which depends upon the
magnitude of intermolecular forces
between the gas particles. Critical
temperatures of ammonia and carbon
dioxide are 405.5 K and 304.10 K
respectively. Which of these gases will
liquify first when you start cooling from
500 K to their critical temperature ?​

Answer 1

Answer:

Higher the critical temperature, more easily the gas liquesfies. As NH3 has higher critical temperature, on cooling down from 500 K, the critical temperature of NH3 will be reached first. Hence, NH3 will be liquefied first CO2 will be liquefied only on further cooling.
