Which of the following is a characteristic of putrefaction? A. Skin tightening
B. Muscle relaxation
C. Bloating
D. A blue discoloration

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
