Definition of Electron Gain Enthalpy Electron gain enthalpy is the energy gained by a gas atom when an electron is accepted to form a negative ion. It is measured in electron volts per atom or kJ per mole (kJ/mol). The easiest method used to determine this energy is the electron gain enthalpy method, which is […]

Generally speaking, a catalyst is any element that accelerates the rate at which a reaction happens without being consumed by the process itself. This means that the substance accelerates the pace at which a chemical reaction occurs without affecting the nature of the material itself. It becomes possible to use an alternate pathway that requires

We get metals from ores of oxides by electrolysis, also called reduction. The ores of oxides can be reduced, but that of carbonates and sulphides is more difficult. These ores can be changed to a metallic state only when the carbonates and sulphides are converted to the ore of an oxide. Either calcination or roasting

The Diels-Alder reaction is an important organic chemical reaction where the reactants include a substituted alkene and a conjugated diene. This substituted alkene is commonly referred to as a dienophile. This reaction gives rise to a substituted derivative of cyclohexene. The Diels Alder reaction is a very good example of pericyclic reactions which proceed via

In numerous chemical processes as well as nuclear reactions, half-life is a specific occurrence that occurs on a daily basis. Imagine that you are at a movie theatre and you are watching a movie. This will give you a good understanding of what half-life is all about. This guy is consuming popcorn from a tub

Decarboxylation is a chemical reaction. The term “decarboxylation reaction” refers to a chemical reaction in which a carboxyl group is removed and carbon dioxide is produced as a result (CO2). Decarboxylation is most commonly associated with a process between carboxylic acids that removes a carbon atom from a chain of carbons. Carboxylation is a totally

Introduction De Broglie wavelength is used to determine the wavelength of matter and hence is used to explain the dual behaviour of matter. This can be explained with the help of examples. De Broglie wavelength formula is demonstrated with a few examples below: It is observed that when a person is riding a bicycle in

Collision theory is a mathematical model for predicting the speeds of chemical reactions, especially in glasses. The collision hypothesis assumes that in order for a reaction to occur, the reacting components (atoms or molecules) must come together or collide with one another. However, not all collisions result in chemical change. Only if the species brought

Combustion and Pyrolysis are two different reactions.  Their difference can be explained in the following way. Combustion is a chemical reaction that produces heat and light in the form of flame and is frequently accompanied by the release of oxygen. Pyrolysis is the process of exposing compounds to extremely high temperatures in comparatively inert environments
