2NO2 +Cl2 ----> 2NO2Cl

mechanism:

NO2 +Cl2 -----> NO2Cl +Cl (Slow step)

NO2 +Cl -----> NO2Cl (fast step)

using the mechanism, draw and energy profile of the reaction showing the relative energy of the reactants and products (this reaction is exothermic), both transition states, intermediates, activation energy for both steps, and the overall change in enthalpy for the reaction (Delta H of the reaction).

    33 5 points The thermal decomposition of nitryl chloride (NO2Cl) as shown below, 2NO+2NO2 + Cl2 is thought to occur as follows: NO2Cl + NO2 + CI (slow step) NO2CI+ CI+NO2 + Cl2 (fast step) The rate law derived from the above mechanism would be: O rate = k[NO2Cl] O rate = k[NO2Cl][CI] O rate = k[NO2][Cl] o rate = k[NO2Ci] O rate = k[NO21[Cl2] Previous
