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

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

    B)  the rate of reaction remains the 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 :

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