    \[N{{O}_{2}}\] (brown colour gas) exists in equilibrium with\[{{N}_{2}}{{O}_{4}}\](colourless gas) as gjlven by chemical equation. \[\underset{(brown)}{\mathop{2N{{O}_{2}}}}\,\underset{(colourless)}{\mathop{{{N}_{2}}{{O}_{4}}}}\,\] Mixture is slightly brown due to existence of\[N{{O}_{2}}\]. If pressure is increased

    A)  colour intensity is increased

    B)  colour intensity is decreased

    C)  colour intensity first increases and then decreases

    D)  No change in colour intensity

    Correct Answer: B

    Solution :

                    By Le-Chateliers principle, due to increase in pressure, equilibrium shifts in the direction of low pressure (in which number of mole decreases) i.e., forward side.
