Relation between errors in enthalpy and entropy

In extracting enthalpy and entropy values from temperature-dependent data, the error in the enthalpy is proportional to the error in the entropy, with a proportionality constant equal to an average temperature of measurement. This proportionality is verified experimentally in two recent studies. It is surprising how often published data do not obey this proportionality, and it is recommended that authors apply this simple procedure to verify their analyses of the temperature dependence of equilibria or rates.
