A mixture initially contains A, B, and C in the following concentrations: [A] = 0.500 M , [B] = 0.800 M , and [C] = 0.350 M . The following reaction occurs and equilibrium is established: A+2B⇌C At equilibrium, [A] = 0.330 M and [C] = 0.520 M . Calculate the value of the equilibrium constant, Kc.

The value of the equilibrium constant is 7.447.

Explanation:

A  +   2B  ⇌  C

Initially

0.500 M   0.800 M   0.350 M

At equilibrium :

(0.500-x) M (0.800-2x)M     (0.350+x)M

Concentration at equilibrium:

[A] = 0.330 M = (0.500-x)M

x = 0.17 M

[B] = (0.800-2x)M  = 0.800 - 2  0.17 M = 0.46 M

[C] = 0.520 M

The expression of an equilibrium constant will be give as:

The value of the equilibrium constant is 7.447.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

c. orbital shape i hope this is correct
