3. This question concerns the dissolution of CO
2
in water.
(a) (5 pts) Write down the equilibrium reactions of the dissolution processes, including Henry's equilibrium, the first dissociation, and the second dissociation.
其他申論題
c) (12 pts) In the troposphere, ozone can be transported from stratosphere but is mainly produced by chemical reactions. Figure 1-2 shows the cyeling of HOx and O3; production in a polluted atmosphere. Please describe in detail how the ozone is formed in the troposphere (you can use CO or CH4 as an example to illustrate the processes).
#420600
(a) (4 pts) Please calculate the total amount of rain over the whole Taiwan per day (in a unit of liter ).
#420601
(b) (6 pts) Please calculate the concentration of HNO; and H2SO4, in the rain, respectively (in a unit of M, 體積莫爾濃度).
#420602
(C) (4 pts) please calculate the resulting rainwater pH (assun ming equilibrium with H2SO4, and HNO3, H2SO4 and HNO3; are strong acids and dissociate completely).
#420603
(b) (5 pts) Ignore the second association and derive the hydronium concentration [H+] as a function of CO2 partial pressure Pcoy, Henry's constant ., first dissociation constant , and water
#420605
(c) (5 pts) Ifthe ocean's pH value is 8 and the dissolved CO2 concet entration is M, try calculated the constant Kw. equilibrium partial pressure of CO2 in the atmosphere (in ppmv) using the following constants:
#420606
(a) (10 pts) Describe aerosol particles' deiiquescence(潮解)and efforescence(脱水) phenomena, and explain their physical-chemical principles.
#420607
(b) (10 pts) The water absorption capacity of a salt particle is different when the air is drying or moisturizing. Explain this hysteresis cycles (遲滯循環) and write down the involved processes.
#420608
(a) (5 pts) How these cloud types differ in composition?
#420609
(b) (5 pts) How these cloud types differ in formation conditions?
#420610
