A comparison of values for the entropy and the entropy of formation of selected organic substances of biological importance in the solid state, as determined experimentally or calculated empirically

The entropy of organic substances can be determined experimentally, using low-temperature calorimetry and the Third Law, by means of the equation Sexp0=∫T=0T0CpdT/T, where the subscript ‘exp’ indicates that the determination is experimental. The entropy of formation of such substances can be determined by means of the equation ΔfSexp0=Sexp0−∑Satoms0, where ∑Satoms0 represents the sum of the standard entropies of the individual atoms in a …
