The branch of science called chemical kinetics does not deal with the

Options

A. rate of reaction
B. factors that influence rate of a reaction
C. reaction mechanism
D. extent of reaction

Answer

D

Explanation

Chemical Kinetics deals primarily with the answers to three questions:
(a) At what rate does a chemical system undergo change under a given set of conditions?
(b) How will a change in conditions affect the rate at which a chemical change occurs?
(c) Given the answers to the first two questions, what information is available about the deails of the chenical change?
Chemical thermodynamics helps us to find the extent of reaction through the knowledge of `k_(eq.)`
Chemical kinetics is a subject of crucial environmental and economic importance. For example, in the upper atmosphere, maintenance or depletion of the ozone layer, which protects us from the sun's harmful ultraviolet radiation, depends on the relative rates of reactions that produce and destroy `O_(3)` molecules. Thus, scientists would like to know whether the nitric oxide `(NO)` in the exhaust gases of supersonic transports will destroy the ozone in the stratosohere faster than the ozone is produced.
In the chemical industry, the profitability of the process for the synthesis of ammonia, which is used as a fertilizer, depends on the rate at which gaseous `N_(2)` and `H_(2)` can be converted to `NH_(3)` .
