Question
Carbonyl fluoride, COF 2 , is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF 4 via the reaction
2COF 2 (g)?CO 2 (g)+CF 4 (g), K c =4.90
If only COF 2 is present initially at a concentration of 2.00 M , what concentration of COF 2 remains at equilibrium?
CO(g)+NH 3 (g)?HCONH 2 (g), K c =0.870
Explanation / Answer
2 COF?(g) ? CO?(g) + CF?(g),
=>
Kc = [CO?] ? [CF?] / [COF?]
