Vedclass · Answer

(C) According to the van der Waals equation,the constant '$a$' represents the magnitude of intermolecular forces of attraction in a gas. Greater the value of '$a$',stronger are the intermolecular forces of attraction. Stronger intermolecular forces make it easier for a gas to be liquefied. Comparing the given values: $SO_2 = 6.71$ $Cl_2 = 6.49$ $NH_3 = 4.17$ $CO_2 = 3.59$ Since $SO_2$ has the highest value of '$a$',it can be most easily liquefied.

Which of the following can be most easily liquefied? (Value of $a$ for $NH_3 = 4.17, CO_2 = 3.59, SO_2 = 6.71, Cl_2 = 6.49$)
