For the following reaction at a certain temperature H2(g) + F2(g) = 2HF(g) the equilibrium concentrations in a 10.00-L rigid container are [H2] = 0.0600 M, [F2] = 0.0200 M, and [HF] = 0.620 M. If 0.220 moles of F2 is added to the equilibrium mixture, calculate the concentration of H2 after equilibrium is reestablished.

Part A It is possible to predict the equilibrium constant of a reaction by combining two or more reactions for which the value of K is known. When combining equilibrium constants, it is important to note the following: Determine the value of the equilibrium constant, Kpal, for the reaction • When a reaction is reversed, its K value is inverted; that is, Kreverse = 1/Kforward- • When the coefficients of a reaction are multiplied by a factor, the K value is raised to the power of that factor. • When reactions are added, their K values are multiplied.
