NEET AIPMT SOLVED PAPER 2002

  • question_answer
                    \[3A\xrightarrow[{}]{{}}B+C\]    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 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 \[\frac{dx}{dt}=\,K[{{A}^{0}}]\]. It means that rate is independent or concentration of reactants.
