Examples of Calorimetric Applications

An arbitrary distinction can be made between chemical reactions and physical changes. Both sorts of change can be equally harmful to the quality of a material. 

Solution phase reactions are, in general, less complex than solid state reactions to study by calorimetry. Reactions are often comparatively fast 

The analysis of the data from 0-5 h gave the results in Table 3, which compare well with the literature value given. 

A rationale of these observations is that the reaction is initially first order with respect to ethyl ethanoate and first order with respect to hydroxy ions, hence second order overall. As the reaction proceeds and
