"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=9.00 if only cof2 is present initially at a concentration of 2.00 m, what concentration of cof2 remains at equilibrium?

Explanation:

The balanced equation is

2COF₂ ⇌ CO₂+CF₄; Kc = 9.00

1. Set up an ICE table

2. Solve for x

3. Calculate the equilibrium concentration of COF₂

c = (2.00 - x) mol·L⁻¹ = (2.00 - 1.50) mol·L⁻¹ = 0.50 mol

OK.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
