For the reaction below at a certain temperature, it is found
that the equilibrium concentrations in a 5.09-L rigid container are
[H2] = 0.0496 M, [F2] = 0.0144 M, and [HF] = 0.478 M.
H2(g) + F2(g) < == > 2 HF(g)
If 0.179 mol of F2 is added to this equilibrium mixture,
calculate the concentrations of all gases once equilibrium is
reestablished.
