Question

Carbonyl fluoride,COF2 , is an important intermediate used inthe production of fluorine-containingcompounds. Forinstance, it is used to make the refrigerant carbon tetrafluoride,CF4 via thereaction

2COF2(g)?CO2(g)+CF4(g),K c=4.90

If only COF2 is present initially at aconcentration of 2.00 M, whatconcentration ofCOF2 remains atequilibrium?

Expressyour answer with the appropriateunits.

B)

Considerthereaction

CO(g)+NH3(g)?HCONH2(g),K c=0.870

If a reaction vessel initially contains onlyCO andNH3 atconcentrations of 1.00 M and 2.00 M ,respectively, what willthe concentrationofHCONH2 be atequilibrium?

Expressyour answer with the appropriate units.
