JEE Main & Advanced Chemistry Chemical Kinetics Question Bank Rate of a reaction

  • question_answer For a given reaction \[3A+B\to C+D\] the rate of reaction can be represented by              [DCE 2000]

    A)                 \[-\frac{1}{3}\frac{d[A]}{dt}=\frac{-d[B]}{dt}=\frac{+d[C]}{dt}=\frac{+d[D]}{dt}\]

    B)                 \[-\frac{1}{3}\frac{d[A]}{dt}=\frac{d[C]}{dt}=K{{[A]}^{m}}{{[B]}^{n}}\]

    C)                 \[+\frac{1}{3}\frac{d[A]}{dt}=\frac{-d[C]}{dt}=K{{[A]}^{n}}{{[B]}^{m}}\]

    D)                 None of these

    Correct Answer: A

    Solution :

                    \[-\frac{1}{3}\frac{d[A]}{dt}=-\frac{d[B]}{dt}=\frac{+d[C]}{dt}=\frac{+d(D)}{dt}\].
