Derive a model for an ideal isothermal plug flow reactor (pfr) in which the reaction 2a + b takes place. let the forward rate constant be k, and the reverse rate constant k2 (both based on a), the reactor cross sectional area be ac, the velocity v ef/a), and the feed concentration caf. initially the rector contains no a. make sure that your model is complete, i. e. it provides all information needed to solve it. classify your model (e. g., linear ordinary differential equations). how do your model equations change if you also assume steady state?

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
