1.) A can of soft drink consists of CO2 dissolved in water and a vapor space filled with CO2 and H2O vapor. Your goal is to find the mole fraction of CO2 in the liquid mixture at 2 bar and 17 C.
a.) Write down the equation that describes the vapor-liquid equilibria for water-vapor in this system and name the variables involved
b.) Write down the equation that describes the vapor-liquid equilibria for CO2 in this system and name the variables involved
c.) What is the Psat of water-vapor at these conditions?
d.) If the Henry’s constant for CO2 at this temperature is 1280 bars, what is the mole fraction of CO2 in the liquid mixture?
e.) What is the Antoine’s equation? What happens to the Psat of a substance as the temperature increases? Explain the behavior in your own words.
