For the reaction
NO + O3 → NO2 + O2
the second order rate constant has a value of 1.8x10-14 molecule-1 cm3 s-1 at 25°C. The concentration of NO in a relatively clean atmosphere is 0.10 ppbv (parts per billion by volume) and that of O3 is 15 ppbv. Calculate these two concentrations in units of molecule cm-3. Calculate the rate of the NO oxidation using concentration units of molecule cm-3. Show how the rate law may be expressed in pseudo-first order terms and calculate the corresponding pseudo-first-order rate constant. Assume the reaction occurs at a pressure of 1 atm.
