Question

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

H.O(g) + C(s) >H(g) + CO(9)
[H2O]
[C]
[Ha]
[CO]

Answer 1

[C]

General Formulas and Concepts:

Chemistry

Kinetics

• Rate Laws

Equilibrium

• Equilibrium Expressions

Step-by-step 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 = ([CO][H])/([H_2O])`.

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