How to determine reaction mechanism from rate law?

If we assume that the reaction follows a first order reaction mechanism (or any other reaction mechanism that follows an elementary reaction), the rate of the reaction can be expressed by the following equation: ra = kb exp(-Ea/RT), where Ea is the reaction activation energy. Now, if we know the rate of reaction at a certain temperature we can determine if the reaction is first order by using the Arrhenius equation: ra = kb exp(Ea/RT - Ea

How to determine reaction mechanism from a rate equation?

For some reactions the rate equation can give information about reaction mechanism, provided the rate law is well-known. For example, a first-order reaction, which involves a single chemical step, is often described by the rate equation which allows you to extract information about the rate from the reaction rate constant. Knowing whether a reaction is first-order is important because it determines whether the reaction follows an ordered pathway or not.

How to determine mechanism of a reaction from rate law?

A rate law can be used to determine the mechanism of a reaction. This is because the rate law is dependent on step or transition, which is one of the reaction mechanisms. If there is no step or transition in the reaction mechanism, then the rate law will not apply to the reaction. Let us take an example to see how to determine reaction mechanism from rate law. Consider the reaction between potassium hydroxide and hydrochloric acid (KOH + HCl → KCl + H2O

How to determine reaction mechanism from the rate equation?

One of the simplest methods to determine reaction mechanism is to use the rate law, which further helps explain the reaction mechanism. The rate law for an elementary reaction can be represented as: rate =

How to tell reaction mechanism from rate law?

The reaction mechanism can be determined using the rate equation. The rate equation for a first-order reaction is:
