1.	Explain why pure liquids and solids can be ignored while writng the equilibrium canstant expression.
Answer» Solution :[Pure liquid ] or [Pure solid] =` (" No. of MOLES ")/(Volume in L) = ("Mass//MOL.mass")/(Volume) = ("Mass")/("Volume")xx 1/("Mol .mass") = ("Density")/(" Mol . Mass") ` As demsity of a pureliquid or pure solid is CONSTANT at constanttemperature and molecularmass is also constant ,therefore , their molar concentrations are constantand included into the EQUILIBRIUM constant .
