twelve orders of soil taxonomy

Carolus Linnaeus - The Father of Modern Taxonomy - Carolus Linnaeus (1707-1778) was a Swedish biologist. He is considered as a pioneer in the field of taxonomy because of two significant contributions. fig. 6.2 -Carolus Linnaeus He made an attempt to classify living organisms to..

Land is also a precious resource. Land is needed for agriculture and occupation. Land is under pressure due to increasing population. Land for agriculture has to be fertile in order to be able to support a good crop. The fertility of land lies in the quality of the soil..

The relative stability of a molecule can be determined on the basis of bond order. It is defined as the number of covalent bonds in a molecule. It is equal to one half of the difference between the number of electrons in the bonding and antibonding molecular orbital..

The order of reaction is determined with respect to each reactant in the reaction. The order of a reaction is the power to which the concentration of a reactant is raised. This is the order with respect to one reactant only. For the reaction where there are more than o..

Calculation of Order of a Reaction from t 1/2 Values - A reaction is carried out at two different initial concentrations of a reactant [A], that is [A] 0 , 1 and [A] 0 , 2 and the respective t 1 / 2 values (t 1 / 2 ) and (t 1 / 2 ) 2 are obtained. The order of the reac..

Similarly, higher order derivatives can also be define..

The differential equation in which only the first derivative of the unknown function appears, is called First order differential equation. Example:..

Series Reactions (First Order) - A complex reaction involving two series reactions can be of the type, A reacts to give B, which is then transformed to C. Both the elementary reactions (1) and (2) exhibit first - order kinetics, that is, For this reaction, [A] = [A] o exp (-k 1 ..

For a reaction A + B C + D. The rate law for the reaction is expressed as rate = k [A] m [B] n If the concentration of B is kept large, then [B] essentially does not change over time and if the rate of reaction is determined as rate = k [A] then this reaction is a pseudo first order react..
