    Consider the reaction, \[CaC{{O}_{3}}(s)CaO(s)+C{{O}_{2}}(g)\]in closed container at equilibrium. What would be the, effect of adding \[CaC{{O}_{3}}\] on the equilibrium concentration of \[C{{O}_{2}}\]?

    A)  Increases

    B)  Decreases

    C)  Remains constant

    D)  None of these

    Correct Answer: C

    Solution :

                    \[K=[C{{O}_{2}}]\] or \[p.C{{O}_{2}}\] since, \[[CaC{{O}_{3}}]\] and \[[CaO]\] are not included in the K (because concentration of solids are taken as unity), there will be no effected of addition of \[CaC{{O}_{3}}\].
