Reaction rates
WebThe reaction rate is this concentration multiplied by the frequency with which they form products, which is known from kinetic theory. Despite the approximations involved in transition-state theory, it has been successful in providing an insight into how chemical reactions occur and how their rates depend on various factors. Molecular dynamics WebThe reaction rate is the speed with which the products are produced and the reactants are consumed in a specific reaction. It is usually discussed in terms of the rate at which one component of the mixture is used up or formed.

WebReaction 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. The rate of decomposition of H 2 O 2 in an aqueous solution decreases as the concentration of H 2 O 2 decreases. WebThe rate of reaction highly depends on the type and nature of the reaction. As mentioned earlier, few reactions are naturally faster than others while some reactions are very slow. …
