Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction COF2(g) yeilds CO2(g) + CF_4(g),kc=4.70 If only \rm COF_2 is present initially at a concentration of 2.00 M, what concentration of \rm COF_2 remains at equilibrium?
