What chemical kinetics?

Answer 1

Chemical kinetics refers to the branch of chemistry that deals with how fast and how reactions happen. An example of this is a gold wedding ring that someone is wearing. Believe it or not, that ring is oxidizing right before your eyes (gasoline is oxidized when you light it!). It just happens so extremely slow that you will never see it in your lifetime! So Chem. kinetics deals with:

1. rates of reaction: how fast does a reaction happen? how does increasing one of the reactants affect the rate of reaction? is it the same as increasing a different reactant?

2. mechanisms of reaction: does the reaction go exactly as written? or are there a few sub steps that happen in relatively quick succession? is one of those sub steps the rate determining step that determines the overall rate of the whole reaction?

Answer 2

Chemical Kinetics is defined as the study of the rate of chemical reaction and the factor that influence the rate. Inother word - study of fast the reaction take place. The factor affects the rate of reaction :

• nature of the reactants
• concentration of reactants
• temperature
• presence or absence of catalyst.

Answer 3

Chemical kinetics is a branch of chemistry that studies the rate at which reactions proceed (both forward and backward). Many chemical reactions, such as rusting, are only spontaneous in one direction which is forward. In this process, iron is oxidized from a 0 state to either a +2 or +3 state; the product is Fe2Ox. This process is only spontaneous (∆G < 0) for the forward reaction. For example, without the input of energy a rusted bolt will not suddenly "unrust" and become a shiny bolt again. The rate of rusting can be either fast or slow; it is usually slow and chemists will study the time it takes to rust (oxidize) and construct a mathematical relationship between the time it takes to rust and the material that is being oxidized. Catalysts lower the activation energy for a reaction and cause it to proceed much more quickly but are not consumed in the reaction. A macro non chemical example of a catalyst would be if you were to put your hand in a calm body of water and circulate the water to cause a non zero curl. Your hand is not "used up" in the process (your hand is still there) but it sped up the circulation of the water. Nuclear kinetics is also a branch of kinetics that studies the rate of nuclear reactions. PET scans use radioactive compounds that expel positrons into space. These compounds must have short half lives in order to avoid bodily harm but remain stable long enough for a complete scan. Kinetics may be one of the most important studies of chemistry because it applies to everyday life. It is very math oriented, and calculus is used to derive equations such as the integrated rate law.

Answer 4

Chemical Kinetics is the area of chemistry that concerns reaction rates.

Answer 5

Chemical kinetics study the rate of chemical reactions and how they happen.

Answer 6

reaction rate.
