The stability of the following alkali metal chlorides follows the order :

Answer»

`LiCl gt KCl gt NaCl gt CS Cl`
`CsCl gt KCl gt NaCl gt LiCl`
`NaCl gt KCl gt LiCl gt CsCl`
`KCl gt CsCl gt NaCl gt LiCl`

Solution :The stability of a compound depends upon its enthalpy of formation , `DELTA H_(f)^(@)` . Evidently more NEGATIVE the value of `DeltaH_(f)^(@)` , more stable is the compound.The VALUES given in parentheses are in kJ `MOL^(-1)`.
