Solution: The reaction A + B ⇌ C + 2D has an equilibrium constant of 3.7 x 10 -3 . Consider a reaction mixture with: [A] = 2.0 x 10-2 M [B] = 1.7 x 10-4 M [C] = 2.4 x 10-6 M [D] = 3.5 x 10-3 M Which of t

Problem

The reaction

A + B ⇌ C + 2D

has an equilibrium constant of 3.7 x 10 -3 . Consider a reaction mixture with:

[A] = 2.0 x 10-2 M

[B] = 1.7 x 10-4 M

[C] = 2.4 x 10-6 M

[D] = 3.5 x 10-3 M

Which of the following statements is definitely true?

  1. No conclusions about the system can be made without additional information.
  2. The system is at equilibrium.
  3. The reverse reaction will occur to a greater extent than the forward reaction until equilibrium is established.
  4. The forward reaction will occur to a greater extent than the reverse reaction until equilibrium is established.
