In the "Méthode Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is C,H12Oe(aq) + 2C,H;OH(ag) + 2C0,(9) Fermentation of 893 mL grape juice (density is 1.0 g/cm) is allowed to take place in a bottle with a total volume of 971 mL until 15% by volume is ethanol (C,HOH). Assuming that CO2 obeys Henry's law, calculate the partial pressure of Co, in the gas phase and the solubility of CO, in the wine at 25°C. The Henry's law constant for CO, is 3.1 x 10-2 mol/L - atm at 25°C with Henry's law in the form C = kP, where C is the concentration of the gas in mol/L. (The density of ethanol is 0.79 g/cm.) (Enter your answers to two significant figures.) Partial pressure= atm Solubility

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
Question
Transcribed Image Text:In the "Méthode Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is
C,H12Os (aq) + 2C, H;OH(aq) + 2002(9)
Fermentation of 893 ml grape juice (density is 1.0 g/cm') is allowed to take place in a bottle with a total volume of 971
mL until 15% by volume is ethanol (C,H; OH). Assuming that CO2 obeys Henry's law, calculate the partial pressure of
CO, in the gas phase and the solubility of CO, in the wine at 25°C. The Henry's law constant for CO, is 3.1 x 10-2
mol/L atm at 25°C with Henry's law in the form C = kP, where C is the concentration of the gas in mol/L. (The density
of ethanol is 0.79 g/cm.)
