    To an equilibrium mixture of \[2S{{O}_{2}}(g)+{{O}_{2}}(g)\rightleftharpoons 2S{{O}_{3}}(g),\] some helium, an inert gas, is added at constant volume. The addition of helium causes the total pressure to double, which of the following is true?

    A)  The concentration of all three gases is unchanged

    B)  The concentration of sulphur trioxide increases

    C)  The number of moles of sulphur trioxide increases

    D)  The concentration of sulphur dioxide increases

    Correct Answer: A

    Solution :

     Since, the inert gas is added at constant volume, ie, the volume is not allowed to increase, the concentrations of all the three gases remain unchanged.
