Saturated vapor pressure of water at 24C is 0.03019 atm, Henry's law constant for CO2 in water is .1102mol/L atm at the same temperature (Henry's law, in this case, is written as pA=1/HcA ), the earth atmosphere has 0.04%CO2. A. Consider a 1L bottle of carbonated water pressurized at 2.4 atm in CO2 and 24C ? a. What would be the concentration of CO2 in the water? b. What would be the mole fraction of CO2 in the water? c. How many grams of CO2 would be dissolved in the water? B. Now if the 1L bottle of water was left open in air at 24C ? a. What would be the concentration of dissolved carbon dioxide (in mole/L)? b. What would be the molefraction of water in the gasphase just above the water? c. What would the concentration of water in the water, number of mole of water/L at 24C and 1atm ? d. If the concentration of CO2 at the air/water interface is 1.2105mole/L and initially there is no CO2 in the water below. What would be the initial diffusional flux (JA) of CO2 in the water if the bottle is 15cm tall and the diffusion coefficient for CO2 in water is 1.79105cm2/s at 24C and 1atm ? e. If the molefraction of water in gas-phase above the water is yw,1=0.03 and the relative humidity of the still air above the bottle is 20% so at 20cm above the water is yw,2=0.006. What would be the diffusional flux (JA) of water in air (from the water surface to 20cm above the surface) if the diffusion coefficient of water in air is 0.15cm2/s
