Nighttime loss of NOx in the lower troposphere proceeds by:
NO + O3 --> NO2 +O2 (1)
NO2 + O3 --> NO3 + O2 (2)
NO2 + NO3 + M <--> N2O5 +M (3)
N2O5 --> 2HNO3 (in aerosol H2O) (4)
Let NO3* represent the chemical family composed of NO3 and N2O5, ie,
[NO3*]=[NO3]+[N2O5]. Calculate the lifetime of NO3* at night.
The nighttime loss of NOx in the lower troposphere proceeds through a series of reactions as given:
- NO + O3 → NO2 + O2
- NO2 + O3 → NO3 + O2
- NO2 + NO3 + M ⇌ N2O5 + M
- N2O5 → 2HNO3 (in aerosol H2O)
Let [NO]0 and [NO2]0 be the initial concentrations of NO and NO2, respectively. Let [NO3*]0 be the initial concentration of NO3* (i.e., [NO3*]0 = [NO3]0 + [N2O5]0).

Leghemoglobin has a binding affinity for oxygen 20 times greater than myoglobin. What function might Leghemoglobin have in the roots of the plant for Nitrogen fixing bacteria? (Hint: The enzyme that catalyzes Nitrogen fixation can also bind O2 , which is not ideal for the enzyme)Considering the following illustration, what is the relationship between plants, animals, O2 and CO2?
- w i 1) Destruction of the ozone layer takes place when its component ozone (03) is converted O3 + 0202 into oxygen gas (O2) as shown by the following chemical equation. Although degradation of O3 happens naturally, there are some man-made substances that cause this process to take pla ce at a rate which is harmful to the environment. One such substance is chlorofluorocarbon or CFC. In the presence of ultraviolet (UV) radiation, a de chlorine (Cl) atom from CFC reacts with O3 and converts it to 02 at a faster rate. This is Cl + O3 → Clo + O2 Clo + 0- Cl + O2 shown by the 2 equations below. In this process, the chlorine atom acts as 2) Pepsin is an enzyme present in gastric juice. In the stomach, it catalyzes the breaking ! down of proteins into shorter polypeptides.
