hear above attachment i told
that .. all about conversion...
I given you only ... Unit conversion ... The rate constant... constant Value is not considered..

9. The reaction 2NO +O2 → 2NO2 is believed to occur by the following mechanism: 2NO ↔ N2O2 N2O2 + O2 → 2 NO2 a. Assume N2O2 to be in a steady state and derive the rate equation for the overall reaction. b. Under what condition does the rate equation reduce to second order kinetics in NO and first order kinetics in O2 at the same time?
19. For the reaction 2NO + O2 + 2NO2 the following reaction mechanism have been suggested; step1: NO + NO NZOZ Fast step 2: N2O2 + O2 k2, 2NO2 Slow and the apparent rate law was found to be R = kes [NO]? What would be the estimated effective activation energy, Eel, value, if the activation energies for forward and backward reactions in step 1 are 82 kJ mol- and 205 kJ mol', respectively, and the activation energy of step...
