1. A reactor with rigid walls (volume 8 I) is filled with 250 ml of oxygen (at 15 atm and 40°C) and 500 ml of CO (at 20 atm and 30°C). Then the conversion of CO to CO₂ occurs. Calculate the partial pressure and the total pressure at the end of the reaction knowing that the temperature reaches 223°C.

CH3CHO + 2H+ + 2e¯ → C2H5OH, with ECH, CHO -0.19 v NAD+ + H+ + 2e¯ → NADH, with E ´NAD+ -0.32 v 1. If acetaldehyde (CH3CHO) and ethanol (C2H5OH) are mixed in the presence of NAD+ and NADH, a chemical reaction starts. Use the information above to determine the balanced chemical equation for the overall reaction that occurs spontaneously. Explain how you know that your reaction proceeds spontaneously in the direction indicated in your chemical equation. 2. In the liver, the enzyme called alcohol dehydrogenase catalyzes the conversion of ethanol to acetaldehyde. If the reaction is allowed to proceed until equilibrium is established, how would the reaction mixture respond to the addition of the enzyme? Explain your reasoning.
