Forward reaction is a reaction in which products are produced from reactants and it goes from left to right in a reversible reaction.
Reversible reaction is a chemical reaction that can proceed in both the forward and backward directions. When reversible reactions reach equilibrium the forward and reverse reactions are still happening but at the same rate, so the concentrations of reactants and products do not change. A reversible reaction is denoted by a double arrow pointing both directions in a chemical equation.
Average rate of reaction is calculated in a way that a total change of reactants and products concentration is divided with time which is needed for reaction to end.
Acylaction reaction involves the introduction of an acyl group (RCO-) into a compound. An alkyl halide is reacted with an alcohol or a carboxylic acid anhydride e.g.
The introduction of an acetyl group (CH3CO-) is acetylation, a process used for protecting -OH groups in organic synthesis.
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.
Electroorganic reaction is an organic reaction produced in an electrolytic cell. Electroorganic reactions are used to synthesise compounds that are difficult to produce by conventional techniques. An example of an electroorganic reaction is Kolbe’s method of synthesising alkanes.
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 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.
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.
Chemical reactions are symbolically shown with chemical equations. On the left side of the equation we write formulas or substance symbols which enter the chemical reaction, reactants. On the right side formulas or substance symbols which emerge from the chemical reaction, products, are writen.
Each chemical reaction leads to an equilibrium which is moved more or less to one side (left or right). Because of that, in reversible reactions instead of = sign two opposite arrows are put
In order to write down certain chemical reaction equation all reactants and all products and their stechiometric proportions must be known. (See Chemical reaction balancing)
