http://en.wikipedia.org/wiki/Elementary_reaction Chemical kinetics has often been understood as an important branch of chemistry. The definition of chemical kinetics is - Rate of reaction. Chemical kinetics is often scruplousky found to be a tough topic, but with a little bit of effort it can be rendered to as a easy and high scoring topic.
There are only a few concepts namely rate law, half life and reaction rate.
Integrated Rate Law is often quoted as an important concept. It consisits of both zero order reaction and molecularity. Molecularity and order are very much similar but have a different meaning all together. Order is defined as the power to which the concentration term is raised while molecularity is defined as the cycloaddition of a compound in case of a chemical reaction.
If we look carefully at the concepts surrounding a chemical reaction. In case of integrated rate law K is defined as the rate constant. This rate constant is often quoted as an indicator of the reaction. -d(a)/dt=d(b)/dt.
The rate of reaction is often qouted as how quickly the reaction can occur.
Half life is quoted as the time taken in completing half of the reaction. it's equation is as follows-
0.693/t(half) = K
where K is the rate constant.
Another important concept that arises is the use of integration. If the reaction is used properly we may find out that
the reaction coefficient is further more possible.
