The rate of the reaction in terms of disappearance of the reactant and appearance of product.
CO(g) + NO2(g) → CO2(g) + NO(g)
Rate of reaction in terms of disappearance of the reactants and appearance of product.
2NO(g) + O2(g) → 2NO2(g)
The rate expression is derived by step II of the mechanism, as it is the slower one
rate = k[NOBr2][NO] ...(i)
However, NOBr2 is an intermediate and thus its concentration should be replaced from equation (i)
From step (i),
Equilibrium constant,
...(ii)
Then by equation (i) and (ii)
Order of the reaction is 2+1 =3
The rate of the reaction in terms of disappearance of the reactant and appearance of product.
2NO2(g) + F2(g) → 2NO2 F(g)
