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.
