a) The equilibrium reaction for the aqueous dissociation of acetic acid is shown below. CH3COOH(aq) = CH3COO-(aq) + H+ (aq) Given the data in the table below and your knowledge of the "chemical standard state" (X) and the “biochemical standard state” (Xº'), answer parts a) to e). c) For the dissociation of acetic acid at 298.15 K, calculate AG and the corresponding pK₁. b) Even though by definition, AfG©(H+ (aq)) = 0 and_AƒGº¹(H+(aq)) = 0, these are different physical quantities. What precisely does each represent? Calculate at 298.15 K, AG' for CH3COOH(aq) and CH3COO¯(aq).
