  • question_answer The decomposition of \[{{N}_{2}}O\] into \[{{N}_{2}}\] and O in the presence of gaseous argon follows second order kinetics with \[=K(5.0\times {{10}^{11}}L\,mo{{l}^{-1}}\,{{S}^{-1}}){{e}^{-29000K/T}}\]Activation energy of the reaction is

    A)  \[121\,KJ\,\,mo{{l}^{-1}}\]             

    B)  \[241\,KJ\,\,mo{{l}^{-1}}\]

    C)  \[201\,KJ\,\,mo{{l}^{-1}}\]     

    D)  \[280\,KJ\,\,mo{{l}^{-1}}\]

    Correct Answer: B

    Solution :

    On comparing the equation of K with \[K=A{{e}^{{}^{-Ea}/{}_{RT}}}\] \[{}^{Ea}/{}_{RT}=29000{}^{K}/{}_{T}\] \[Ea=(29000\,K)R=241\,KJ\,mo{{l}^{-1}}\]
