Dissociation (chemistry) - Wikipedia
The degree of dissociation in gases is denoted by the symbol α where α refers to the percentage of gas molecules which dissociate. Various relationships between Kp and α exist depending on the stoichiometry of the equation. The example of dinitrogen tetroxide (N2O4) dissociating to nitrogen dioxide (NO2) will be taken. If the initial concentration of dinitrogen tetroxide is 1 mole per litre, this will decrease by α at equilibrium giving, by stoichiometry, 2α moles of NO2. The equilibrium constant (in terms of pressure) is given by the equation; Where p represents the partial pressure. Hence, through the definition of partial pressure and …

Dissociation | chemistry | Britannica
Dissociation, in chemistry, the breaking up of a compound into simpler constituents that are usually capable of recombining under other conditions. In electrolytic, or ionic, dissociation, the addition of a solvent or of energy in the form of heat causes molecules or crystals of the substance to break up into ions (electrically charged particles). Most dissociating substances produce ions by chemical combination with the solvent.

What is Dissociation? - Definition from Corrosionpedia
Mar 08, 2018 · Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner, as do CO 2 and H 2 O at high temperatures. Dissociation is …

Dissociation | Chemistry for Non-Majors
Dissociation. An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds.

What does dissociate mean in chemistry?
Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner, as do CO 2 and H 2 O at high temperatures. Dissociation is the opposite...

How does dissociation work chemistry?
Corrosionpedia explains Dissociation. Dissociation in chemistry is a general process in which molecules separate or split into smaller particles. For instance, when an acid dissolves in water, a covalent bond between an electronegative atom and a hydrogen atom is broken by heterolytic fission, which gives a proton (H+) and a negative ion.
