Multiple Choice
Which statement is true regarding the reversible reaction below? H2CO3+ F-
HCO3+ HF.
Ka1(H2CO3) = 4.2 × 10-7; Ka(HF) = 7.1 × 10-4
A) At equilibrium, [HF] > [H2CO3] because HF is a stronger acid than H2CO3.
B) At equilibrium, [HF] > [H2CO3] because H2CO3 is a stronger acid than HF.
C) At equilibrium, [HF] = [H2CO3].
D) At equilibrium, [H2CO3] > [HF] because HF is a stronger acid than H2CO3.
E) At equilibrium, [H2CO3] > [HF] because H2CO3 is a stronger acid than HF.
