    \[C{{l}_{2}} (g)+3{{F}_{2}}(g)\,\,\,2Cl{{F}_{3}}(g);\,\,\Delta H,=-\,329kJ\] The above reaction represents an exothermic process. Which of the following will increase quantity of \[Cl{{F}_{3}}\] in an equilibrium mixture?

    A)  \[Removing\text{ }C{{l}_{2}}\]

    B)  \[Adding\,\,{{F}_{2}}\]

    C)  Increasing temperature

    D)  Increasing the volume of container

    Correct Answer: B

    Solution :

    \[\because ~\,\,\,\,\Delta {{n}_{g}}=\,\,-\,ve\] \[\therefore ~\,\,\,\,\Delta H\,\,=\,\,-\,ve\] Hence, reaction will undergo shift towards forward direction of extra amount of \[{{\operatorname{F}}_{2}} or C{{l}_{2}}\] added.
