Assume that the reaction for the formation of gaseous hydrogen fluoride (HF) from hydrogen (H2) and fluorine (F2) has an equilibrium constant K = [HF]2 / [H2][F2] of 1.15×10 2 at a certain temperature. In a particular experiment at this temperature 3.000 mol of each component were added to 1.500 mL flask. Calculate the equilibrium concentration of all species using an ICE table. Let x equal the number of moles per litre of H2 consumed to reach equilibrium.
