  • question_answer
    The exothermic formation of \[Cl{{F}_{3}}\] is represented by the equation: \[C{{l}_{2(g)}}+3{{F}_{2(g)}}\rightleftharpoons 2Cl{{F}_{3(g)}}\];  \[\Delta H=-329\,KJ\] Which of the following will increase the quantity to \[Cl{{F}_{3}}\] in an equilibrium mixture of\[C{{l}_{2}},\,{{F}_{2}}\] and \[Cl{{F}_{3}}\]?

    A) Increasing the temperature

    B) Removing \[C{{l}_{2}}\]

    C) Increasing the volume of container

    D) Adding \[{{F}_{2}}\]

    Correct Answer: D

    Solution :

    [d] Favorable condition for forward reaction according to Le Chatelier principle are:
    (i) Decrease in temperature
    (ii) Increase in concentration of reactant
    (iii) Increase in pressure
