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),    K=7.80 at 850 K

If only COF2 is present initially at a pressure of 252 kPa, what is the partial pressure of COF2 at equilibrium?

You can convert the units of pressure from kPa to bar, using the relation 1 kPa=0.01 bar.

 PCOF2 = 0.383 bar

Correct

Part B

Consider the reaction

CO(g)+NH3(g)⇌HCONH2(g),    K=2.70 at 550 K

If a reaction vessel initially contains only CO and NH3 at partial pressures of 2.00bar and 2.20 bar, respectively, what will the partial pressure of HCONH2 be at equilibrium?

PHCONH2 =

11.88bar

Incorrect; Try Again; 8 attempts remaining

CO(g)   +   NH3(g) <----------------->   HCONH2(g)

2.0 bar       2.2 bar                                     0

2 - x           2.2 - x                                        x

K = [HCONH2] / [CO][NH3]

2.70 = x / (2-x)(2.2 -x)

x = 1.378

P HCONH2 = x = 1.378 bar
