The reaction of nitrogen dioxide with carbon monoxide

NO2 + CO NO + CO2

is second order in NO2 and zero order in CO.

1.Complete the rate law for this reaction in the box below.
Use the form k[A]m[B]n... , where '1' is understood for m, n ...(don't enter 1) and concentrations taken to the zero power do not appear.

Rate =

2.In an experiment to determine the rate law, the rate constant was determined to be 0.790 M-1s-1. Using this value for the rate constant, the rate of the reaction when [NO2] = 1.23 M and [CO] = 0.221 M would be ______Ms-1

Answer :

Answer:

(1) Rate = k[NO2]^2[CO]

(2) The rate of the reaction is 1.195 Ms^-1

Explanation:

(1) Equation of reaction

NO2 + CO = NO + CO2

The reaction is second-order in NO2 and zero-order in CO

Therefore, rate = k[NO2]^2[CO]^0

(2) Rate = k[NO2]^2[CO]^0

k = 0.790 M^-1s^-1

[NO2] = 1.23 M

[CO] = 0.221 M

Rate = 0.79×1.23^2×0.221^0 = 1.195 Ms^-1
