  • question_answer
    The rate law of the reaction \[2{{N}_{2}}{{O}_{5}}\to 4N{{O}_{2}}+{{O}_{2}}\] is [MP PET 2002]

    A)                 \[r=K[{{N}_{2}}{{O}_{5}}]\]         

    B)                 \[r=K{{[{{N}_{2}}{{O}_{5}}]}^{2}}\]

    C)                 \[r=K{{[{{N}_{2}}{{O}_{5}}]}^{0}}\]          

    D)                 \[r=K{{[N{{O}_{2}}]}^{4}}[{{O}_{2}}]\]

    Correct Answer: A

    Solution :

               Rate law for the reaction                    \[2{{N}_{2}}{{O}_{5}}\to 4N{{O}_{2}}+{{O}_{2}}\]                                 is \[r=k[{{N}_{2}}{{O}_{5}}]\] first order reaction.
