    \[4moles\]each of \[S{{O}_{2}}\] and \[{{O}_{2}}\] gases are allowed to react to form \[S{{O}_{3}}\] in a closed vessel. At equilibrium 25% of \[{{O}_{2}}\] is used up. The total number of moles of all the gases at equilibrium is:

    A)  \[6.5\]  

    B)  \[7.0\]

    C)  \[8.0\]

    D)  \[2.0\]

    Correct Answer: A

    Solution :

    \[2S{{O}_{2}}+{{O}_{2}}2S{{O}_{3}}\]
    initrally \[4\] \[4\] \[0\]
    atequil \[4(1-0.25)\] \[4(1-0.25)\] \[0.25\times 2\]
    Total number of moles at equilibrium \[=4(1-0.25)+4(1-0.25)+0.5\] \[=4-1+4-1+0.5=6.5\]
