A closed system initially containing 1.000 × 10-3 M H2 and 2.000 × 10-3 M I2 at 448℃ is allowed to reach equilibrium. At equilibrium, the HI concentration is 1.87 × 10-3 M. Given that the reaction equation is H2(g) + I2(g) ↔ 2 HI(g), find:
a. Equilibrium concentrations of the two reactants
b. Kc of the reaction taking place.

For N2(g) + 3 H2(g) ↔ 2 NH3(g), Kp = 4.34 × 10-3 at 300℃. What is Kp or the reverse reaction?
