Please help with this. I am stuck
The mechanism for the thermal decomposition of NO_2 is given below. Mechanism for the thermal decomposition of NO_2. NO_2(g) + NO_2(g) N_2O_4(g) N_2O_4(g) N_2O_3(g) + O(g) N_2O_3(g) + O(g) N_2O_2(g) + O_2(g) N_2O_2(g) 2 NO(g) Identify the intermediates in this reaction. Choose all that apply. NO_2 N_2O_4 N_2O_3 O N_2O_2 O_2 NO There are no intermediates in this reaction What is the role of NO in this reaction? reactant product intermediate catalyst Identify the catalysts in this reaction. Choose all that apply. NO_2 N_2O_4 N_2O_3 O N_2O_2 O_2 NO There are no catalysts in this reaction.Explanation / Answer
A.N2O2 is a correct option.
Explanation- NO2 is a reactive intermediate, not a reactant or a product. We should eliminate it from the rate law.
B. Product is correct option
Explanation – It appears in last equation as a product.
C. O is the catalyst in this reaction.
Explanation-The decomposition of nitrogen dioxide is such that the atomic oxygen released
in the initial step reacts very rapidly with the remaining nitrogen dioxide and consumes atomic oxygen quite fast.
