Part A

Carbonyl fluoride, COF2COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4CF4 via the reaction

2COF2(g)⇌CO2(g)+CF4(g),    Kc=6.402COF2(g)⇌CO2(g)+CF4(g),    Kc=6.40

If only COF2COF2 is present initially at a concentration of 2.00 MM, what concentration of COF2COF2 remains at equilibrium?

Part B

Consider the reaction

CO(g)+NH3(g)⇌HCONH2(g),    Kc=0.870CO(g)+NH3(g)⇌HCONH2(g),    Kc=0.870

If a reaction vessel initially contains only COCO and NH3NH3 at concentrations of 1.00 MM and 2.00 MM, respectively, what will the concentration of HCONH2HCONH2 be at equilibrium?

Express the molar concentration numerically to three significant figures.
