Question 27

Chemical Equilibrium

In what way is equilibrium constant for the forward reaction related to that of the reverse reaction?

  1. A.The addition of the two is expected to be one
  2. B.The product of the two is expected to be one.
  3. C.The two equilibrium constants are identical
  4. D.The product of the two is always greater than one
Show the answer and explanation

Answer: B (The product of the two is expected to be one.)

Explanation

Writing the reverse reaction turns the expression upside down, so Kreverse = 1/Kforward. Multiplying them gives 1.
