factors influencing the rate of a reaction

Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidation of ferrous ion by KMNO 4 (potassium permanganate) in acidic medium is fast, ..

The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case of gas phase reactions), pH, ..

The amounts of reactants and products in a chemical reaction are related by stoichiometry. Therefore, the concentration of any reactant or product can be used to express the rate of a reaction. Take for e.g., in the reaction A + B C for every molecule of A co..

The average rate of reaction is calculated by determining the difference in [O 2 ] concentration over different intervals of time and dividing the difference by D ..

Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example..

Calculation of Average Rate of Reaction - Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtain..

During the formation of monosubstituted products in benzene as all the six hydrogens are equivalent any of the six positions can be occupied. But, when the monosubstituted product is to be converted into disubstituted one, the existing substituent present in the ring directs the incoming group to ..

Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is limited by the most limiting factor..
