Abstract
The subject of this article is the service-oriented architecture utilization in the design and implementation of a web service that is intended to perform selected thermochemical calculations for chemical reactions. Computing functions allow the chemical reaction calculations, such as molar heat capacity, enthalpy, entropy and Gibbs free energy. In the next part, there is a description of each function, the method of service calling in the client application and the structure specification of outputs and error states of the service. In addition to computing functions, the web service also has a group of three information functions that characterize the purpose of the web service and its parameters, provide in tabular form a list of all web service functions and a list of all error states of the web service. The final section describes the presentation web service application with a demonstration of the specific calculations, the possibilities of using the service, and a further solution treatment.
Highlights
The basic tasks of chemical and process engineering mainly include an analysis of existing processes, design of new processes, construction of technological equipment, optimizing the use of material and energy flows, monitoring, indirect measurement of process quantities and process control itself [1,2,3,4,5]
For the implementation of thermochemical calculations, there is currently a large number of software tools created using different information technologies. These technologies and program tools based on them begin at simple spreadsheets and desktop applications, continue with network applications using HTML and various server scripts and end at a service-oriented architecture [8] (SOA) through the web services [9] or enterprise services bus (ESB) [10], which is optionally applied in the form of a cloud computing [11] (CC)

Summary
The basic tasks of chemical and process engineering mainly include an analysis of existing processes, design of new processes, construction of technological equipment, optimizing the use of material and energy flows, monitoring, indirect measurement of process quantities and process control itself [1,2,3,4,5]. For the implementation of thermochemical calculations, there is currently a large number of software tools created using different information technologies These technologies and program tools based on them begin at simple spreadsheets and desktop applications, continue with network applications using HTML and various server scripts and end at a service-oriented architecture [8] (SOA) through the web services [9] or enterprise services bus (ESB) [10], which is optionally applied in the form of a cloud computing [11] (CC). The relationship between the WS, SOA, and CC can be shown in the form of the Venn diagram [8] (Fig. 1) In this diagram, the WS is concluding (encapsulating) the CC because the CC uses the WS for the purposes of connection. The article is a contribution in the field of thermochemical calculations using web services and provides the possibility of its use in different areas
