The equilibrium constant Kc is 1.6 × 105 at 1297 K and 3.5 × 104 at 1495 K for the reaction

H2(g) + Br2(g) ⇌ 2HBr(g)

a. Is ΔrH° for this reaction positive or negative?

b. Calculate Kc at 1297 K for the reaction

1/2H2(g) + 1/2Br2(g) ⇌ HBr(g)

c. Pure HBr is placed into an evacuated container of constant volume. The container is sealed and heated to 1297 K. Calculate the percentage of HBr that is decomposed to H2 and Br2 at equilibrium.
