EVERYDAY SCIENCE

Detailed explanation-1: -chemical kinetics, the branch of physical chemistry that is concerned with understanding the rates of chemical reactions.

Detailed explanation-2: -Chemical Kinetics is the study of reaction rates, how reaction rates change under varying conditions and by which mechanism the reaction proceeds.

Detailed explanation-3: -Chemical kinetics is the study of the rates of chemical reactions or how fast reactions occur. The primary requirement for a reaction to occur is that the reactant particles (atoms or molecules) must collide and interact with each other in some way.

Detailed explanation-4: -Thermodynamics-the study of how and why energy moves-governs what can happen in a chemical reaction. By applying the laws of thermodynamics, chemists can measure, predict, and control the heat and energy of chemical reactions to help solve problems like making cleaner-burning rocket fuels and more efficient engines.

Detailed explanation-5: -Summary. A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. A reaction that occurs in two or more elementary steps is called a multistep or complex reaction. A reaction intermediate is a chemical species that is formed in one elementary step and consumed in a subsequent step.
