Question

Consider the formation of hydrogen fluoride:

H2(g) + F2(g) ↔ 2HF(g)

If a 2.4 L nickel reaction container (glass cannot be used because it reacts with HF) filled with 0.0053 M H2 is connected to a 3.6 L container filled with 0.028 M F2. The equilibrium constant, Kp, is 7.8 x 1014 (Hint, this is a very large number, what does that imply?) Calculate the molar concentration of HF at equilibrium.
