Part A 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 --> <-- CO2+CF4 ... KC=5.70 If only COF2 is present initially at a concentration of 2.00 M , what concentration of COF2 remains at equilibrium? Express the molar expression numerically
