2. Fast chemical reactions These are those chemical reactions which take place at a very fast rate. These reactions can take place in seconds or in minutes. In general the reactions between ionic compounds are fast. For example, combustion of LPG gas in kitchen takes place in a few seconds so it is a fast reaction.

In carboxylic acid: Reactions .hydrolysis is base is called saponification, because soap (Latin: sapo) has always been manufactured by heating fats (which are carboxylic esters) with water and a basic substance (originally wood ash). Soap is a mixture of salts of longchain fatty acids.

Slow reactions Chemical reactions that occur very slowly and can take a long time for completion are called slow reactions. Usually covalent compounds are involved in slow reactions. Some reactions can take days, weeks and months to complete; they are called very slow Read More ...

Chemical equilibrium reactions require reversible reactions that can form a dynamic equilibrium, these concepts are also covered here. The equilibrium constant. The equilibrium constant is used to determine whether reactants or products are favoured in a reaction at chemical equilibrium.

Reversible reactions and Equilibrium. REMINDERS about reversible reactions before learning about CHEMICAL EQUILIBRIUM. A reversible reaction is a chemical change in which the products can be converted back to the original reactants under suitable conditions. This means the reaction can go in either direction

A reversible chemical reaction is that in which the reaction is not completed 100 per cent, that is, there is an equilibrium conversion that corresponds to an infinite reaction time. By thermodynamics, it is shown that the total Gibbs free energy of a closed system at constant temperature and pressure should diminish during an irreversible ...

Mar 15, 2019· Researchers quantified a strong, beneficial, and reversible (over hundreds of cycles) chemical reaction involving oxygen ions in the crystal lattice of battery electrode materials. The results open up new ways to explore how to pack more energy into batteries with electrodes made out of lowcost, common materials.
