Consider the reaction that converts pyruvic acid (CH3COCOOH) into gaseous acetaldehyde (CH3CHO) and gaseous CO2, which is catalyzed in aqueous solution by the enzyme pyruvate decarboxylase. Assume that gases behave ideally.

a. Calculate ΔrG∘ (298 K) for this reaction.
b. Calculate ΔrG (298 K) for this reaction at 130 bar.
c. State any important assumptions needed in addition to ideal gas behavior.

Check all that apply.

a. CH3COCOOH remains gase at 298 K and 130 bar.
b. CO2 remains gase at 298 K and 130 bar.
c. CH3CHO remains gase at 298 K and 130 bar.
d. None of the above.
