spontaneous reactions can be slow

Slow reactions are reactions that can be measured in the laboratories. e.g., hydrolysis of est..

If k 1 is very much less than k 2 that is k 1 << k 2 then the intermediate B is transformed into the product C as soon as it is forme..

Example 11: The rate constants of reaction at 700 K and 760 K are 0.011M - 1 s - 1 and 0.105 M - 1 s - 1 respectively. What are the values of 'A' and 'E..

In order to find out some other factor that may be responsible for the feasibility of a process, let us examine endothermic reactions. The simplest process occurring without any energy change (where D H is almost zero) may be illustrated with the help of following experimen..

In order to find out some other factor that may be responsible for the feasibility of a process, let us examine endothermic reactions. The simplest process occurring without any energy change (where D H is almost zero) may be illustrated with the help of following experiment. fig 4.4 (b) ..

It is a well-known fact that all physical and chemical processes are accompanied by energy changes. It is possible to interpret various spontaneous processes on the basis of changes in energy. Consider the spontaneous processes such as falling of a cricket ball from our hands t..

The reactions between covalent compounds occur between their molecules. These involve the breaking of covalent bonds in reacting molecules and forming new covalent bonds to give molecules of the products. These reactions are quite slow because energy is required to br..

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 the reaction depends on the concentration of the reactant. Initially the rate is fast and then it slows down as the concentration of the reactant fall..
