Determine the direction the reaction will proceed to counteract these stresses AND establish how the concentration of fluorine (F2) is expected to change.
ii. 1.5 x 10-3 mol dm-3 and 3.0 x 10-3 mol dm-3 of hydrogen and fluorine gas, respectively, were present in a closed system at 285 oC. At equilibrium, it was found that the concentration of hydrogen fluoride (HF) was 2.8 x 10-3 mol dm-3 . Calculate the value of Kc at 285 oC.
iii. What physical factor will change the value of Kc for this reaction.
