question 23

Multiple Choice

The value of the equilibrium constant for the following reaction is 0.200 at a given temperature: 2HI(g) ⇌ H₂(g) + I₂(g) If [HI] = 0.200 M, [H₂] = 0.200 M, and [I₂] = 0.200 M, determine if the reaction is at equilibrium. If it is not, in which direction will it proceed to reach equilibrium?

• A)The reaction is at equilibrium.
• B)The reaction is not at equilibrium, it will shift to the left.
• C)The reaction is not at equilibrium, it will shift to the right.
• D)It is not possible to tell if the reaction is at equilibrium.
• E)To reach equilibrium, the value of K_eq must change.
