CHEMISTRY GLOSSARY

chain reaction    →   lančana reakcija

Chain reaction is a reaction done in three steps: initiation in which usually radicals are made which react with other molecules in stage of propagation and, when all reactants are spent, it ends by termination when all available radicals are completely spent.

Nuclear chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. Nuclear power plants operate by precisely controlling the rate at which nuclear reactions occur. On the other hand, nuclear weapons are specifically engineered to produce a reaction that is so fast and intense it cannot be controlled after it has started.

terminal reaction    →   terminalna reakcija

Terminal reaction is a reaction that ends a cycle or chain of other chemical reactions.

chemical reaction    →   kemijska reakcija

Chemical reaction is a change of chemical properties of substances which react with each other. By means of a chemical reaction new substances are created by bond breaking between atoms and molecules of reactants and their reuniting in a new way, thereby creating products. Chemical reactions can be shown by chemical equations.

elementary reaction    →   elementarna reakcija

Elementary reaction is a reaction that occurs in a single step. Equations for elementary reactions show the actual molecules, atoms, and ions that react on a molecular level.

endothermic reaction    →   endotermna reakcija

Endothermic reactions are the ones in which heat is absorbed and are facilitated by an increase in temperature (ΔH° > 0).

If the reaction is endothermal in one direction, in the opposite direction the reaction is exothermal.

Faradaic reaction    →   Faradejska reakcija

Faradaic reaction is a heterogeneous charge-transfer reaction occurring at the surface of an electrode.

forward reaction    →   napredna reakcija

Forward reaction is a reaction in which products are produced from reactants and it goes from left to right in a reversible reaction.

heterogenic reaction    →   heterogena reakcija

Heterogenic reactions are those reactions which take place in different phases (in different aggregate states).

homogenic reaction    →   homogena reakcija

Homogenic reactions are those reactions in which products and reactants are in the same phase (aggregate state).

Mannich reaction    →   Mannichova reakcija

Mannich reaction is a process in which hydrogen atoms in organic compounds are replaced with a methyl group.
