ABSTRACT
Article is dedicated to creating and implementing a web service ThermoChemDC designed to address selected thermochemical calculations of chemical reactions for the purposes of process modeling in the acquisition and processing of raw materials. These calculations include the calculation of the heat capacity change, calculate the heat of reaction, calculate the change in entropy calculation of Gibbs free energy and calculate the logarithm of the equilibrium constant. Web service is the dominant representative of service-oriented architecture, which is briefly described in the introductory part of the contribution. The second part of the article deals with the characteristics of selected tools for supporting thermochemical calculations. The main part of article is devoted to the description of the ThermoChemDC web service itself, where are further specified the purpose of web service, basic mathematical relationships of selected thermochemical calculations, individual service functions and their parameters, output, and error XML structure of service. The web service is implemented as a class called ThermoChemDC in PHP5 development environment. The following section contains a description of error states of web service, followed by a brief description of algorithms of individual functions. The penultimate section is devoted to ways and means of using web service together with a specific illustration demonstration. In conclusion, the results obtained are summarized and outlined the way forward in addressing the issue.

Keywords: SOA, web service, thermochemical calculations, PHP
