    For the reaction,\[a+A+bB\xrightarrow[{}]{{}}cC,\]if \[-3\frac{d[A]}{dt}\] \[=-3\frac{d[B]}{dt}=+1.5\frac{d[C]}{dt}\]then a, b and c  respectively are

    A)  1, 3, 2                  

    B)  1, 2, 3   

    C)  3, 2, 1                                  

    D)  3, 1, 2

    Correct Answer: A

    Solution :

                    Dividing throughout by 3, we get \[-\frac{d[A]}{dt}=-\frac{1}{3}\frac{d[B]}{dt}\] \[=+\frac{1}{2}\frac{d[C]}{dt}\] The reaction is \[A+3B\xrightarrow[{}]{{}}2C\]
