    What is the order of a reaction which has a rate expression, rate\[=k{{(A)}^{3/2}}{{(B)}^{-1}}?\]

    A)  3/2                                       

    B)  ½

    C)  0                                            

    D)  None of these

    Correct Answer: B

    Solution :

                    Order of reaction: The total number of molecules or atoms whose concentration determine the rate of a reaction is known as order of reaction. Order of reaction = sum of exponents of the cone. term in the rate law rate =\[k\,{{[A]}^{3/2}}{{[B]}^{-1}}\] \[\therefore \] Order of reaction\[=\frac{3}{2}+(-1)=\frac{1}{2}=0.5\]
