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=6.30 If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium?

The equilibrium concentration of is 0.332 M

Explanation:

We are given:

Initial concentration of = 2.00 M

The given chemical equation follows:

Initial:          2.00

At eqllm:     2.00-2x          x      x

The expression of for above equation follows:

We are given:

Putting values in above expression, we get:

Neglecting the value of x = 1.25 because equilibrium concentration of the reactant will becomes negative, which is not possible

So, equilibrium concentration of

Hence, the equilibrium concentration of is 0.332 M

the answer is 1 i believe
