Reactant concentration chang

WebDec 2, 2024 · The states which contain the species (whose concentration is changed) are affected whereas others are not, so the Gibbs free energies of activation are changed, which means the rate constants are changed, which can change the rate determining step. But if concentrations can affect k r then it seems like the rate law cannot be written like that. WebSince the reactant concentration decreases as the reaction proceeds, Δ [H 2 O 2] is a negative quantity. Reaction rates are, by convention, positive quantities, and so this negative change in concentration is multiplied by −1. The table below provides an example of data collected during the decomposition of H 2 O 2.
