The Acidity Constant,K_a,differs from the Equilibrium Constant,K_eq,for the Dissociation of the Same

Multiple Choice

A) K_a can be determined experimentally with less accuracy than K_eq.
B) The two terms are identical numerically.
C) K_a is used for strong acids only; K_eq for weak acids.
D) K_a is the reciprocal of K_eq.
E) K_eq = K_a/[H₂O].
