WebMar 3, 2015 · In principle, there are no zeroth-order reaction. Experimentally, however, zeroth-order rate law occurs because of the reaction condition. For example, in catalytic … WebPseudo-First order. A very important case is that of pseudo-first order kinetics. This is when a reaction is 2nd order overall but is first order with respect to two reactants. This is a very common kinetic scheme. r a t e = k [ A] [ B] where A and B are some generic reactants. Now the kinetics of this reaction can be a bit complicated.
