    \[3A\xrightarrow[{}]{{}}B+C\] It would be a zero order reaction when:                                            [AIPMT 2002]

    A) the rate of reaction is proportional to square of concentration of A

    B) the rate of reaction remains same at any concentration of A

    C) the rate remains unchanged at any concentration of B and C

    D) the rate of reaction doubles if concentration of B is increased to double

    Correct Answer: B

    Solution :

    [b] For reaction \[3A\xrightarrow[{}]{{}}B+C\]
    If it is zero order reaction, therefore the rate remains same at any concentration of \['A'\] or \[\frac{dx}{dt}=\,K[{{A}^{0}}]\]. It means that rate is independent or concentration of reactants.
