WebUnsymmetrical error limits of +3 and -0.5 (x10 -13) in the A -factor and =320K and -200K reported, partly due to deviation in the high-temperature rate constants. Assuming this is due to a scission reaction, a corrected rate expression was derived for the temperature range 228-292 K: k = (1.4 +8-1)x10-13exp [ (-810±400/T] cm3s-1. 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.
