The concentrations of reactants and products for a chemical
reaction can be calculated if the equilibrium constant for the
reaction and the starting concentrations of reactants and/or
products are known.
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=7.40
If only COF2 is present initially at a concentration of 2.00
M, what concentration of COF2 remains at equilibrium?
