The decrease of the average rate of a reaction with time is illustrated in Table 11 − 2 . The reason behind this decrease is to be stated. The dependence of the instantaneous rate of a reaction on time is to be explained. The reason behind the use of initial rates by convention is to be determined. Concept introduction: The change in the concentration of the reactant involved in a chemical reactionor the product formed in a chemical reaction in a stated time interval is known as the average rate of a reaction, whereas the rate of a reaction observed at any instant of time is known as the instantaneous rate of a reaction.

Photochemical smog is formed in part by the action of light on nitrogen dioxide. The wavelength of radiation absorbed by NO2 in this reaction is 197 nm.(a) Draw the Lewis structure of NO2 and sketch its π molecular orbitals.(b) When 1.56 mJ of energy is absorbed by 3.0 L of air at 20 °C and 0.91 atm, all the NO2 molecules in this sample dissociate by the reaction shown. Assume that each absorbed photon leads to the dissociation (into NO and O) of one NO2 molecule. What is the proportion, in parts per million, of NO2 molecules in this sample? Assume that the sample behaves ideally.
