Question

Explain why pure liquids and solids can be ignored while writing the equilibrium constant expression.

Solution
Verified by Toppr

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.
