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=6.40 if only cof2 is present initially at a concentration of 2.00 m, what concentration of cof2 remains at equilibrium?

The concentration of at equilibrium has been 0.33 M.

The balanced chemical equation for the given reaction has been:

Since the initial concentration of has been 2 M, by applying ICE, the concentration can be:

I          2                  0               0

C       -2x               +x              +x

E      2 - 2x             x                 x

The value of has been the ratio of the product concentration to reactant concentration.

for the given reaction will be:

=

6.40 =

By simplifying the above equation,

x = 0.835 M.

The concentration of at equilibrium has been 2 - 2x

2 - 2x = 2 - 2 (0.835)

The concentration of = 0.33 M.

The concentration of at equilibrium has been 0.33 M.
