Question
The concentration of a pure solid or liquid phase is not included in the expression of equilibrium constant because
Options
A.solid and liquid concentrations are independent of their quantities.
B.solid and liquids react slowly.
C.solid and liquids at equilibrium do not interact with gaseous phase.
D.the molecules of solids and liquids cannot migrate to the gaseous phase.
Solution
[Solid] or [Pure liquid] = $\frac{n}{V} = \frac{w/M}{w/d} = \frac{d}{M} = \frac{\text{Density}}{\text{Molar mass}}$
Thus, it is independent from their quantity.
