For the reaction below at a certain temperature, it is found that the equilibrium concentrations in a 5.01-L rigid container are [H2] = 0.0486 M, [F2] = 0.0133 M, and [HF] = 0.455 M. H2(g) + F2(g) equilibrium reaction arrow 2 HF(g) If 0.177 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibrium is reestablished.
