The value of the equilibrium constant at a given temperature for the reaction:
2HI(g) ⇌ H2(g) + I2(g)
is 0.200. If [HI] = 0.200 M, [H 2] = 0.200 M, and [I 2] = 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 Keq must change.
