    The decomposition of NH3 on platinum surface is zero order reaction. What are the rates of production of N2 and H2 if k = 2.5 × 10-4 mol-1 L s-1?
    Ans : The decomposition of NH3 on platinum surface is represented by the following equation.



    Therefore,



    However, it is given that the reaction is of zero order.

    Therefore,



    Therefore, the rate of production of N2 is



    And, the rate of production of H2 is



    = 7.5 × 10-4 mol L-1 s-1
