a)A possible mechanism for the reaction 2NO+O22NO2 is 1.NO+NON2O2k12.N2O22NOk23.N2O2+O22NO2k3 i) Apply stegdy state approximation, to obtain a rate law in terms of cencentration of NO and O2 ii) If g olx a yex small fraction of all N2O2 formed goes to give product in Eqn. (2) and If the activation energies E1=82kJ/mol,E2=95kJ/mol,E3=82kJ/mol, What is the observed activation energy. b) Consider the following mechanism to describe the overall reaction. A+BD Mechanism: 1. step 2. step 2. step 3. step k12AA2k1 k 2 k2 A2+Ck3D+2Aslow What is the rate equation derived from above mechanism
