At a particular temperature, K = 1.00×102 for the reaction:

H2(g) + F2(g) 2HF(g)

In an experiment, at this temperature, 1.10 mol of H2 and 1.10 mol of F2 are introduced into a 1.08-L flask and allowed to react. At equilibrium, all species remain in the gas phase.

What is the equilibrium concentration (in mol/L) of H2?

What is the equilibrium concentration (in mol/L) of HF?

To the mixture above, an additional 3.63×10-1 mol of H2 is added.

What is the new equilbrium concentration (in mol/L) of HF?
