Based on 1 review. Catalyst forms temporary bonds with the reactants and forms an intermediate complex which soon decomposes to yield products and the catalyst used remains the same or chemically unchanged. This activated complex exists for a very short time interval and gets converted into a product. Study of chemical reactions concerning the rate of reaction, the formation of intermediates, rearrangement of atoms, and the effect of different variables is called chemical kinetics. Those reactions which are not of 1st order but approximated or appears to be of 1st order due to higher concentration of the reactant/s than other reactant are known as pseudo first order reactions. Chemical kinetics is an important aspect of a chemical reaction as it predicts at what rate the reaction will attain equilibrium which helps us to know how we can use this chemical change in a better way. This unstable intermediate is called an activated complex. In this method if we draw a graph between log[A] (where A is a reactant and [A] is concentration of reactant A) and t (time) and it’s a straight line then reaction follows a first order. The word kinetics comes from the Greek language word ‘kinesis’ which means movement. While if we draw a graph between $\frac{1}{[A]^{2}}$ and t and get a straight line then the reaction is a third order reaction. The average rate of reaction – The change in concentration of any of the reactants or products per unit time over a specific time period is called average rate of reaction.
