A gas chromatography column containing a (diphenyl)0.65(dimethyl)0.35polysil oxane stationary phase is used to separate the following molecules. Place the molecules in the order they will elute from the column. A list of retention indexes for several molecules can be found here. -butanol 1-nitropropane 2-pentanone -octane - nonane -decane

the millers tale is the answer.

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.
