The interaction energy of London forces between two particles is proportional to \(r ^{ x }\), where \(r\) is the distance between the particles. The value of \(x\) is
[JEE Main 2021, 26 Aug (Shift 2)]
-6
\(E \propto r ^{-6}\) where \(E\) is the interaction energy of London forces.
Thus, \(x =-6\).
A mixture of \(N_2\) and \(A r\) gases in a cylinder contains \(7 \mathrm{~g}\) of \(\mathrm{N}_2\) and \(8 \mathrm{~g}\) of Ar. If the total pressure of the mixture of the gases in the cylinder is 27 bar, the partial pressure of \(\mathrm{N}_2\) is :
[Use atomic masses (in \(\mathrm{g} \mathrm{mol}^{-1}\) ) : \(\mathrm{N}=14\), \(\mathrm{Ar}=40\) ]
