    The rate law for the reaction, \[2X+Y\to Z\]is \[Rate=k\,[X][Y].\]The correct statement with regard to this relation is

    A)  the rate of reaction is independent of [X] and [V]

    B)  for this reaction \[{{t}_{1/2}}\] is independent of initial concentration of reactants

    C)  the unit of \[k\] is \[{{S}^{-1}}\]

    D)  the rate of formation of Z is half the rate of disappearance of X

    Correct Answer: D

    Solution :

     \[2X+Y\to Z\] According to equation, 2 moles of X on reaction with 1 mole of Y gives 1 mole of Z. In other words, the rate of formation of Z is half the rate of disappearance of X.
