Which Statement Is True Regarding the Reversible Reaction Below? H₂CO₃

question 104

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.

Definitions:

Steps Continuously

A term that likely refers to a process or mechanism that operates in a smooth, uninterrupted progression but is not a standardized technical term. NO.

Start Winding

Winding on a motor that provides additional torque during startup to help the motor reach operating speed.

Split-phase Motor

An AC electric motor that uses a split-phase induction to create a rotating magnetic field for starting torque.

Stator Core

The stationary part of an electric generator or motor, especially the magnetic core, around which the winding is arranged.
