The equilibrium constant, K , of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. For a gaseous reaction with the general form aA+bB⇌cC+dD the Kc and Kp expressions are given by Kc=[C]c[D]d[A]a[B]b Kp=(PC)c(PD)d(PA)a(PB)b The subscript c or p indicates whether K is expressed in terms of concentrations or pressures. Equilibrium-constant expressions do not include a term for any pure solids or liquids that may be involved in the...

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.
