7. Suppose for a synthesis of hydrogen fluoride from hydrogen and fluorine, 3.000 moles of H2 and 6.000 moles of F2 are mixed in a 3.000-L flask. Assume that the equilibrium constant for the synthesis reaction at this temperature is 1.15x102.

H2 (g) + F2 (g) ↔ 2HF (g)

                                                                                                       

What is the molar concentration of HF at equilibrium?

                                                                                                       

What is the molar concentration of F2 at equilibrium?

                                                                                                       

At a Kc of 4.15x103, predict the direction of the reaction if the starting concentrations are [H2]=2.30 M, [F2]= 1.25x10-3 M, and [HF]= 4.37 M
