NH_(3) gas is liquefied more easily than N_(2) . Hence

Assertion (A) Gases do not liquefy above their critical temperature, even on applying high pressure. Reason (R) Above critical temperature, the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed.

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) . It 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 (Tc). The pressure required to liquefy a gas at this temperature is called the critical pressure (Pc). The volume occupied by one mole of the substance at the critical temperature and pressure is called critical 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 values of critical volumes of four gases A, B, C and D are 0.025L, 0.312L, 0.245L and 0.432L respectively. The gas with larger molecular diameter will be :

Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperature and pressure. The reasons for this can be traced to the fact:

O_(2) and SO_(2) gases are filled in ratio of 1 : 3 by mass in a closed container of 3 L at temperature of 27^(@)C . The partial pressure of O_(2) is 0.60 atm, the concentration of SO_(2) would be

Assertion : Lower the cirtical temperature for a gas, more easily can it is liquefied. Reason : Critical temperature is the temperature above which above which a gas cannot liquefied depending upon the pressure.
