Molar balance in open and closed systems with chemical reaction

Molar balance in open and closed systems with chemical reaction 

The kinetic experiments are carried out in reactors in closed or open systems. There are three common cases  

For kinetic purposes, the variation of the concentration or the pressure with reaction time is accompanied in a batch reactor. In a continuous or open system, the pressure is constant and the concentrations or molar flows of the reactants and products are accompanied in the course of the reaction or along the reactor. The time is substituted by an equivalent variable called space time. The space time takes into account the inlet volumetric flow of the reactants and the volume of the reactor, and, thus, has unit of time, here designated by
