    In the chemical reaction\[2S{{O}_{2}}+{{O}_{2}}\xrightarrow{{}}2S{{O}_{3}}\]increasing the total pressure leads to:

    A)  increase in amount of\[S{{O}_{3}}\]

    B)  increase in partial pressure of\[{{O}_{2}}\]

    C)  increase in the partial pressure of\[S{{O}_{2}}\]

    D)  change in equilibrium constant

    E)  none of the above

    Correct Answer: A

    Solution :

    For the chemical reaction \[\underbrace{\underset{2\,mol}{\mathop{2S{{O}_{2}}}}\,+\underset{1\,mol}{\mathop{{{O}_{2}}}}\,}_{3\,mol}\xrightarrow{{}}\underset{2\,mol}{\mathop{2S{{O}_{3}}}}\,\] Here the volume is decrease therefore, increasing the total pressure leads to increase in the amount of\[S{{O}_{3}}\].
