Question

Which one will liquefy most easily when compressed at a constant temperature?

A. F2
B. H2
C. HF
D. SiH4
E. Ar

and why?

Answer 1

\[[P+a(N ^{2}divV ^{2})][V-Nb]=NRT\] is the van der waal's gas equation.Now Here b represent the size of the molecule collectively,and a represent the force of attraction one molecule exerts over other.Higher the value of 'a' and smaller the value of 'b' the greater the compressibility of the gas.
