The Vander Waal’s constant ‘a’ for the gases

{O_2},{N_2},N{H_3}\,\mathrm{and}\,\,C{H_4}

are 1.360, 1.390, 4.170, 2.253

{L^2} \cdot atm \cdot mo{l^{ - 1}}

respectively. The gas which can be most easily liquefied is

View answer and explanation

Correct option: C

N{H_3}

Option C (

N{H_3}

) is correct because it has the highest 'a' value, indicating stronger intermolecular forces and easier liquefaction.

A quantity of hydrogen gas occupies a volume of

30 \mathrm{~mL}

at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas? In deriving the kinetic equation we make use of the root mean square speed of the molecules which is: Consider the following statements for kinetic molecular theory of gases
a. Particles of a gas move in all possible directions in straight lines.
b. At any particular time, different particles in the gas have different kinetic energies.
c. Collisions of gas molecules are perfectly inelastic in nature.
The correct statement(s) is/are The compressibility factor of an ideal gas is The relative strength of interionic/intermolecular forces in decreasing order is Compressibility factor of an ideal gas is
