Answer:

[C]

General Formulas and Concepts:

Chemistry

Kinetics

  • Rate Laws

Equilibrium

  • Equilibrium Expressions

Explanation:

Equilibrium Expressions are only written for either aqueous solutions or gases. Solids and liquids are negligible for equilibrium. Our equilibrium constant expression would be [tex]\displaystyle K = \frac{[CO][H]}{[H_2O]}[/tex].

∴ Carbon C (s) is not included in the expression and is our answer.
