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.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
