There are three images that are attached in order of the question :) The oxidation of NO(g) producing NO2(g is represented by the chemical equation shown above. (see attached document) The initial concentrations of NO and O2 are given in the table above. The changes in the concentration of NO(g) as a function of time are shown in the following graph. (see attached document). Under the same conditions, one of the following graphs represents the changes in the concentration of O2(g) over the same period of time. Which graph best represents the changes in concentration of 02(g), and why? (see attached document) a.) Graph 1, because the rate of O2 consumption is half the rate at which NONO is consumed; two molecules of NO react for each molecule of O2 that reacts. b.) Graph 1, because O2 molecules are consumed at a slower rate at the beginning of the reaction when there are not as many molecules of NO2 produced.

a.) Graph 1, because the rate of O2 consumption is half the rate at which NONO is consumed; two molecules of NO react for each molecule of O2 that reacts.
b.) Graph 1, because O2 molecules are consumed at a slower rate at the beginning of the reaction when there are not as many molecules of NO2 produced.
c.) Graph 2, because there is a large excess of O2 molecules and its concentration will not change drastically over time.
