Acetylcholinesterase catalyzes the reaction in which acetylcholine is hydrolyzed into acetate and choline. This is a reversible reaction. A student incubates a 1 M solution of acetylcholine for two hours with 100uL of acetylcholinesterase. At equilibrium the concentration of acetylcholine is 3.0 × 10 mM and the concentration of acetate and choline are 5.2 × 10^-3M and 7.4 x 10^-2 M, respectively.
Calculate the equilibrium constant (K_eq) and the standard state free energy ( $\Delta$ G°') for this reaction at 17°C.
