Multiple Choice

Which statement is true regarding the reversible reaction below? H2CO3+ F-
Which statement is true regarding the reversible reaction below? H<sub>2</sub>CO<sub>3</sub>+ F<sup>- </sup> <sup> </sup>   HCO<sub>3</sub>+ HF. K<sub>a1</sub>(H<sub>2</sub>CO<sub>3</sub>)  = 4.2 × 10<sup>-7</sup>; K<sub>a</sub>(HF)  = 7.1 × 10<sup>-4</sup> A)  At equilibrium, [HF] > [H<sub>2</sub>CO<sub>3</sub>] because HF is a stronger acid than H<sub>2</sub>CO<sub>3</sub>. B)  At equilibrium, [HF] > [H<sub>2</sub>CO<sub>3</sub>] because H<sub>2</sub>CO<sub>3</sub> is a stronger acid than HF. C)  At equilibrium, [HF] = [H<sub>2</sub>CO<sub>3</sub>]. D)  At equilibrium, [H<sub>2</sub>CO<sub>3</sub>] > [HF] because HF is a stronger acid than H<sub>2</sub>CO<sub>3</sub>. E)  At equilibrium, [H<sub>2</sub>CO<sub>3</sub>] > [HF] because H<sub>2</sub>CO<sub>3</sub> is a stronger acid than HF. HCO3+ HF.
Ka1(H2CO3) = 4.2 × 10-7; Ka(HF) = 7.1 × 10-4
