Question

You mixed a solution that initially contained 0.010 M H2 and 0.0080 M I2 at 25 ˚C. The following reaction occurred.
H2 + I2 < - - > 2HI
At equilibrium, [HI] = 0.0030
Determine the equilibrium constant of the reaction, Kc, for this reaction at 25 ˚C

Answer 1

Begin by writing an I.C.E. table (initial, change, equilibrium concentrations)

then substitute the values from E. into the equilibrium expression for the reaction.
