Answer the following :

Noble gases have very low boiling points. Why?

MEDIUM

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Amongst He, Ne, Ar and Kr; 1 g of activated charcoal adsorbs more of Kr.

Reason R: The critical volume Vc (cm3 mol1) and critical pressure Pc (atm) is highest for Krypton but the compressibility factor at critical point Zc is lowest for Krypton.

In the light of the above statements, choose the correct answer from the options given below.
