  • question_answer
    The rate equation for the reaction \[2A+B\to C\] is found to be: rate \[=k[A][B]\]. The correct statement in relation to this reaction is that the [AIEEE 2004]

    A)                 Rate of formation of C is twice the rate of disappearance of  A

    B)                 \[{{t}_{1/2}}\]is a constant

    C)                 Unit of k must be \[{{s}^{-1}}\]

    D)                 Value of k is independent of the initial concentrations of A and B

    Correct Answer: D

    Solution :

               For \[2A+B\to C\]                    Rate\[=K[A][B]\]                                 Value of rate constant \[K=A{{e}^{-Ea/RT}}\] here K is independent of the initial concentration of A and B.
