(a).

Complete the following equilibrium table.

2HI(g)       ⇌   H2(g) + I2(g)

Initial                         0.1600 M        0          0

Change                                                           

─────────────────────────────

Equilibrium    

(b). Determine equilibrium values for [HI] and [H2]if [I2] = 0.0227 M at equilibrium.

                   2HI(g)       ⇌    H2(g) + I2(g)

I                 0.16                  0         0

C              -2*0.0227        0.0227 0.0227

E            0.16-2*0.0227 0.0227   0.0227

              0.1146

                Kc = [H2][I2]/[HI]2

                        = 0.0227*0.0227/(0.114)2    = 0.039

Kc>Qc the equilibrium shift ot right side.
