Question

Part A

Carbonyl fluoride, COF2, is an important intermediate used inthe production of fluorine-containing compounds. For instance, itis used to make the refrigerant carbon tetrafluoride, CF4 via thereaction

2COF2(g)?CO2(g)+CF4(g), Kc=8.20

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

Express your answer with the appropriate units.

Part B

Consider the reaction

CO(g)+NH3(g)?HCONH2(g), Kc=0.650

If a reaction vessel initially contains only CO and NH3 atconcentrations of 1.00 M and 2.00 M,respectively, what will the concentration of HCONH2 be atequilibrium?

Express your answer with the appropriate units.
