## Question:

The following data was collected for the reaction between carbon monoxide and nitrogen dioxide. The time recorded response to a NO contraction change of 2.7×10⁻³ M.

NO2+CO--->NO+CO2

 Trial (NO2) (CO) Time (s) 1 0.020 0.010 296 2 0.030 0.010 197 3 0.020 0.020 74

A) Calculate the rate for each of the three trials?

B) Determine the order of the reaction with respect to NO2.

C) Determine the order of the rxn with respect to CO.

D) What is the rate constant?

E) What is the rate law equation for this reaction?

## Rate constant

It is a coefficient relating the rate of a chemical reaction at a given temperature to the concentration of the reactant. It changes with temperature and its units depend on the sum of the concentration.
