WebJan 30, 2024 · Video transcript. - [Instructor] The Pre-equilibrium Approximation is used to find the rate law for a mechanism with a fast initial step. As an example, let's look at the reaction between nitric oxide and bromine. In the first step of the mechanism, nitric oxide combines with bromine to form NOBr2. And in the second step of the mechanism, NOBr2 ... WebFeb 2, 2024 · The reaction progression at different temperature conditions can also be seen with the reaction modulus σ 2, which is the non-dimensional parameter representing the relative importance of the chemical reaction kinetics and the diffusion on the reaction, thus a useful parameter to get a quick glimpse of the dominating reaction regime. According ...
