    The rate constant of a reaction is \[10.8\times {{10}^{-5}}\] \[mol\,\,d{{m}^{-3}}\,{{s}^{-1}}\]. The order of the reaction is

    A)  zero                                     

    B)  1

    C)  2                                            

    D)  3

    Correct Answer: A

    Solution :

                    Units of rate constant for n order reaction \[={{(mol/L)}^{1-n}}{{s}^{-1}}={{(mol\,d{{m}^{-3}})}^{1-n}}{{s}^{-1}}\] On comparing these units with the given units of rate constant, we get \[{{(mol\,d{{m}^{-3}})}^{1}}{{s}^{-1}}={{(mol\,\,d{{m}^{-3}})}^{1-n}}{{s}^{-1}}\] Thus, the order of the reaction is zero.
