Consider the formation of hydrogen fluoride:
H2(g) + F2(g) ↔ 2HF(g)
If a 4.9 L nickel reaction container (glass cannot be used because it reacts with HF) filled with 0.0078 M H2 is connected to a 3.1 L container filled with 0.029 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.
