Kinetics is the study of rates of chemical reactions. Kinetics allows the chemists to predict how the speed of a reaction will change under a reaction conditions. The study of kinetics is very important because it can elucidate the information about the mechanism of a reaction and can also allow chemists to be more efficient in the laboratory. At higher concentrations a reaction will proceed more quickly. In a step wise reaction, the rate determining step (RDS) is the step with the highest energy transition state, also known as slow step. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
