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