  • question_answer 90) It th6 rate constant of a reaction is \[2\times {{10}^{-3}}{{s}^{-1}},\]What is the order of reaction?

    A)  0                            

    B)  1    

    C)  2                                            

    D)  3

    Correct Answer: B

    Solution :

                    Units of rate constant \[={{\left( \frac{mol}{L} \right)}^{1-n}}.\,\,{{(time)}^{-1}}\] Given units of rate constant \[={{s}^{-1}}\]              On comparing, we get                       \[1-n=0\] \[\therefore \]  \[n=1\]            Thus, the order of reaction is first.
