1. For: 2COF2(g) ↔ CO2(g) + CF4(g) the Kc value is 2.0 x 10-4

For: 6COF2(g) ↔ 3CO2(g) + 3CF4(g) the Kc value is 8.0 x10-12

True
False

2. For the system: 2CO(g) + O2(g) ↔ 2CO2(g) ; decreasing the volume of the container will shift the equilibrium:

A. left
B. no shift
C. right

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

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=8.70

If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium?
