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 2cof2(g)⇌co2(g)+cf4(g), kc=5.30 if only cof2 is present initially at a concentration of 2.00 m, what concentration of cof2 remains at equilibrium?
