WebbIn the case of a first order reaction, e.g. a cis-trans isomerisation, the rate is d [ A] / d t = − k 1 [ A] and the rate constant k 1. As you can see from the Arrhenius equation the rate constant ( k 1, k 2) depends on temperature and the rate depends on concentration of both A and B and the rate constant. WebbThe reaction though of second-order is experimentally found to be first-order. Thus it is a pseudo-first-order reaction. ZERO ORDER REACTIONS In a zero order reaction, rate is independent of the concentration of the reactions. Let us consider a zero-order reaction of the type A ⎯⎯→ Products Initial conc. a 0 Final conc. a – xx 0 ...

In the determination of reaction orders and rate constant, one of the common used technique is known as the method of excess. WebbHowever, the estimated reaction rate constants assuming pseudo-1st order reaction agree with those reported based on batch studies. TCE degradation rate was proportional to concentration. This was considered to be the result of using high inflow concentrations of reactant, which might be the case at the vicinity of the source zones in aquifer.
