Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. Order of reaction can be positive integer – Positive integer value of order of reaction indicates that the concentration of the reactants directly affect the rate of a reaction. 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. Change in rate of reaction can be easily explained by the Arrhenius equation. On rearranging the equation (6), we get –, \[\frac{1}{[A]_{t}}\] = kt + \[\frac{1}{[A]_{0}}\] _ _ _ _(7), On comparing equation (7) with straight line equation or linear equation y = mx + c, we can write –. Chemical kinetics relates to many aspects of cosmology, geology, and even in some cases, psychology. In the same way the amount of time required by reactant/s to undergo decay by half in second order reaction is called half life of second order reaction.

Chemical kinetics is that branch of chemistry which deals with the study of the speeds or the rates of chemical reactions, the factors affecting the rates of the reactions and the mechanism by which the reactions proceed. Few examples of second order reaction are given below –, Nitrogen dioxide decomposes into nitrogen monoxide and oxygen. For determination of molecularity only rate determining step is considered. As we shall see in later chapters, this is almost universal in enzyme kinetics, where not even the simplest enzyme-catalyzed reac-tions have simple orders. It is the number of molecules taking part in the rate determining step. For a successful collision, following conditions must be followed –, Reactant molecules must collide with each other, Molecules should collide in the proper orientation. For 1st order reactions – In[R] = -kt + In[R]0, k = \[\frac{1}{t_{2} - t_{1}}\] ln\[\frac{[R]_{1}}{[R]_{2}}\]. Equation (11) is the equation for half life of second order reaction. Change in rate of reaction can be easily explained by the Arrhenius equation. Thus, in chemical kinetics we can also determine the rate of chemical reaction. Unit of reaction rate (r) is moles per liter per second (mol.L-1.s-1) and the unit of second order rate constant is M-1.s-1 (M is molarity which can be expressed as mol/L). Suppose one mole of a reactant A produces one mole of product B and their concentration at time t1 is [A]1 and [B]1 respectively. Section 12 General Chemistry Notes - Chemical Kinetics. Reaction Rates Rate of a chemical reaction = change in concentration (mol/L) of a reactant or product with time (s, min, hr); Rate of Reaction= 4. Chemical Kinetics Factors That Affect Reaction Rates • Physical State of the Reactants In order to react, molecules must come in contact with each other. A reaction is called a second order reaction when the overall order is two. That’s why when we cook food at low temperature (low gas), it takes time to cook while at high temperature (high gas), it cooks faster. For example, we can know how rapidly food material get spoiled by predicting the rate of the chemical change which is taking place in the food material. Click here.
