 particular temperature, K = 1.00×10reaction.

experiment,temperature, 1.90 mol of H2 and 1.90 mol of F2  introduced  1.25-L flask and allowed react.  equilibrium, all species remain  gas phase.What's equilibrium concentration (in mol/L) of H2?

H2 + F2===2HF

So 1.90 mol of H2 and 1.90 mole of F2 will completely react to 3.80 moles of HF.

Therefore the equilibrium concentration of H2 would be 0.
