For the following reaction Kc= 2.00 at1000 degrees celsius.

2COF2(g) --><--- CO2(g) + CF4(g)

A 5.00 L moisture contains 1.40 mol COF2, 0.264 mol CO2 and8.0x10^-2 mol CF4 at a temperature of 1000 degrees celsius.


How many moles of each gas will be present at equilibrium?

COF2, CO2, CF4

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(g)?CO2(g)+CF4(g), Kc=6.20
If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2remains at equilibrium?

Part B
Consider the reaction
