18.8: Rate Law and Specific Rate Constant - Chemistry LibreTexts
the reaction rate is described by = [] [], where is a bimolecular rate constant. Bimolecular rate constants have an upper limit that is determined by how frequently molecules can collide, and the fastest such processes are limited by diffusion.Thus, in general, a bimolecular rate constant has an upper limit of k … Meer weergeven In chemical kinetics a reaction rate constant or reaction rate coefficient, k, quantifies the rate and direction of a chemical reaction. For a reaction between reactants A and B to form … Meer weergeven The Arrhenius equation is an elementary treatment that gives the quantitative basis of the relationship between the activation energy and … Meer weergeven The units of the rate constant depend on the global order of reaction: If concentration is measured in units of mol·L (sometimes abbreviated as M), then • For order (m + n), the rate constant has units of mol ·L ·s (or M ·s ) • For order zero, the rate … Meer weergeven For an elementary step, there is a relationship between stoichiometry and rate law, as determined by the law of mass action. Almost all elementary steps are either … Meer weergeven For a first-order reaction (including a unimolecular one-step process), there is a direct relationship between the unimolecular rate constant and the half-life of the reaction: $${\textstyle t_{1/2}={\frac {\ln 2}{k}}}$$.
