The order of a reaction in some species seems an obvious, trivial concept that all chemists master. However, in complex situations such as catalytic systems, the order of a reaction is not always that simple: it can be partial, negative and function of other parameters. In order to analyze...

The overall order is defined as the sum of the exponents of all concentrations in the rate equation. For example, a reaction with rate equation −rA=kCA2CB is second order in A, first order in B, and third order overall. Reaction orders are in general empirical quantities, deduced from ...
Sizes of arrows qualitatively reflect relative reaction rates within each biochemical step. b, Comparison of denAsCas12a-KRAB (D908A/E174R/S542R/K548R) versus multiAsCas12a-KRAB (R1226A/E174R/S542R/K548R) in CRISPRi knockdown of CD81 expression assayed by flow cytometry 10 days after...
Consider a tubular reactor where a chemical reaction changes the concentration of the fluid as it moves down the tube. Assuming first-order chemical reaction, isothermal reactor, and constant density, the modeling equation is (3)∂CA∂t=−vz∂CA∂z+DAz∂2CA∂z2−kCA where z is...
