Pseudo-irreversibility functional

Subscript j is unnecessary when there is only one chemical reaction. When the kinetics are second-order, irreversible, and only a function of Ca, the dimensionless pseudo-volumetric reaction rate, based on bulk gas-phase concentrations, is... 

When a reactor is charged with liquid A and B is a gas that is added continuously, it becomes a semibatch reactor. The rates of reaction depend on the concentration of B in the liquid phase, which is a function of gas solubility, pressure, and agitation conditions. However, we are often concerned with the relative reaction rates and the selectivity, which do not depend on Cb if the reaction orders are the same for both reactions. The reactions are treated as pseudo-first-order, and equations are developed for an ideal batch reactor with irreversible first-order kinetics...
