Question

The values of van der Waal's constant "a" for the gases O2​, N2​, NH3​ and CH4​ are 1.36, 1.39, 4.17, 2.253 L2 atm mole−2 respectively

the order of liquefication is​

Answer 1

Answer:

van der waal's constant 'a' is a measure for the attraction between the particles. Higher the value of 'a' stronger the force between gas particles and easy to compress them in liquid. Thus, NH

among the gases can easily liquified.
