What is the numerical value of Kc for the following reaction if the equilibrium mixture at 750 °C contains 0.20 M CO and 0.052 M CO2?

FeO(s) + CO(g) ⇌ Fe (s) + CO2 (g)

The answer to your question is    Kc = 0.26

Explanation:

Data

Kc = ?

[CO] = 0.20 M

[CO₂] = 0.052 M

For this problem, do not consider the concentration of the reactants and products in a solid-state.

Formula

           Kc =

Substitution

           Kc =

Simplification and result

           Kc = 0.26

The equilibrium constant Kc is 0.26

Explanation:

Step 1: Data given

The equilibrium mixture contains 0.20 M of CO and 0.052 M of CO2

Step 2: The balanced equation

FeO(s) + CO(g) ⇌ Fe (s) + CO2 (g)

Step 3: Calculate Kc

Pure solids and liquids are not included in the equilibrium constant expression. This is because they do not affect the reactant amount at equilibrium in the reaction, so they are disregarded and kept at 1. Remember that the activity, a, of any solid or liquid in a reaction is equal to 1

Kc = [CO2] / [CO]

⇒with [CO] = 0.20 M

⇒with [CO2] = 0.052 M

Kc = 0.052 / 0.20

Kc = 0.26

The equilibrium constant Kc is 0.26

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
