rate of reaction

In the absence of PAN formation, the only sink for NOx is oxidation to HNO3:

NO2 + OH + M  HNO3 + M (6)

We calculate the rate of reaction (6) as d[NO2]/dt = -k6[NO2], where k6 = 1x10-5

s-

1 is a simplified pseudo first-order rate constant. The main simplification

involved in the formulation of k6 is that we make no distinction between night and

day; instead, a 24-hour average OH concentration is built into k6. We assume

that HNO3 is rapidly removed by deposition and cannot be recycled back to NOx.

What is the lifetime of NOx? Calculate the concentration of NOx in the air parcel

as a function of time from t=0 to t=10 days. What is the concentration of NOx

remaining after 10 days?
