In a precipitation reaction the extent to which a precipitate is formed is dependent on the solubility product constant of the precipitate. a species with a highly soluble large k may not precipitate until very high consentrations are reached. a species with a insoluble low k will precipitate readiliy. why will the formation of a precipitate increase when non stoichiometric amounts of reactants are used? ?

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
