3. Calculate the pH of natural rainwater at 25Â°C, given that the CO2 concentration in air is 372 ppm (present level), and that for carbon dioxide the Henryâs Law constant Kh = 3.4x10-2 mol/l/atm and Ka for H2CO3 has a value of 4.5x10-7 mol-L. Assume that the following reaction is the only significant source of acidity: H2CO3 = HCO3 - + H+

5. A power plant burns 10,000 metric tons of coal (assume it is pure C) per day and emits stack gas with 100 ppmv NO. If it uses 10% excess air (which is 21 mol% O2), what is the daily output of NO?

As discussed in class, the pH of otherwise clean water inequilibrium with the atmosphere is about 5.6. This calculationassumes an atmospheric carbon dioxide concentration of 300 ppm =10^-3.5 atm. As a result of the combustion of fossilfuels and other factors, the atmospheric CO₂concentration is increasing. What is the pH of clean water inequilibrium with the atmosphere if the atmospheric CO₂concentration increases to 350 ppm? 600 ppm?
