Carbonyl fluoride, COF 2 , is an important intermediate used inthe production of fluorine-containing compounds. For instance, itis used to make the refrigerant carbon tetrafluoride, CF 4 via thereaction 2COF 2 (g)â‡ŒCO 2 (g)+CF 4 (g), K c =9.00 If only COF 2 ispresent initially at a concentration of 2.00 M , what concentrationof COF 2 remains at equilibrium? Thanks! ( I keep getting .1 butthat is incorrect)

Equilibrium constant, K_c = ([CO₂ ][CF₄ ]) / [COF₂ ]²

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 9.00 = (a x a) / (2-2a)²

Therefore the concentration of COF₂ remain at equilibrium = 2-2a
