AIPMT 2009 Preliminary Mock Test

The energy absorbed by each molecule ($A_2$) of a substance is $4.4\times 10^{-19}\text{J}$ and bond energy per molecule is $4.0\times 10^{-19}\text{J}$. The kinetic energy of the molecule per atom will be:

Amongst the elements with following electronic configurations, which one of them may have the highest ionization energy?

In the reaction ${\text{BrO}}_3^{-}(aq)+5{\text{Br}}^{-}(aq)+6{\text{H}}^{+}\to 3{\text{Br}}_2(l)+3{\text{H}}_2\text{O}(l)$. The rate of appearance of bromine (${\text{Br}}_2$) is related to rate of disappearance of bromide ions as following:

A $0.0020\text{m}$ aqueous solution of an ionic compound ${\text{Co(NH}}_3{)}_5({\text{NO}}_2)\text{Cl}$ freezes at $-0.00732^{\circ }\text{C}$. Number of moles of ions which $1\text{mol}$ of ionic compound produces on being dissolved in water will be ($k_f=1.86^{\circ }\text{C/m}$):

What is the dominant intermolecular force or bond that must be overcome in converting liquid ${\text{CH}}_3\text{OH}$ to a gas?
