Question

Which will not appear in the equilibrium constant expression for the reaction below?

Answer 1

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 $\displaystyle K = \frac{[CO][H]}{[H_2O]}$.

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