question 110

Multiple Choice

Which statement is true regarding the reversible reaction below? H₂CO₃+ F^- HCO₃+ HF.K_a1(H₂CO₃) = 4.2 × 10^-7; K_a(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.
