Question

1A)

A mixture initially contains A, B, and C in the following concentrations: [A] = 0.300 M , [B] = 1.15 M , and [C] = 0.400 M . The following reaction occurs and equilibrium is established:

A+2B⇌C

At equilibrium, [A] = 0.190 M and [C] = 0.510 M . Calculate the value of the equilibrium constant, Kc.

1B)

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=6.10

If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium?

Answer 1

1A) Equilibrium constant (K_c​​​​​​) =3.1

1B) Concentration of COF₂ at equilibrium = 0.34 M
