Strictly speaking the above equation holds also for devices with chemical reactions Should the conditions from the equilibrium equation are taken to make reference to whole mass, i.e. the sum of many of the chemical species of your procedure. In the absence of the chemical response the quantity of any chemical species flowing in and out would be the identical; This offers rise to an equation for every species existing within the procedure. Nonetheless, if it's not the case then the mass balance equation need to be amended to allow to the technology or depletion (intake) of each chemical species. Some use just one term In this particular equation to account for chemical reactions, which will be unfavorable for depletion and positive for generation.
