Define constant in chemistry
WebMay 19, 2024 · Activation energy is the minimum amount of energy required to initiate a reaction. It is the height of the potential energy barrier between the potential energy minima of the reactants and products. Activation energy is denoted by E a and typically has units of kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). WebAdult Education. Basic Education. High School Diploma.

WebMay 20, 2024 · This constant may be called a stability constant or association constant; the units depend on the specific reaction it is describing. Common metal/ligand \(K_f\) values are tabulated in Table E4 . At its most basic level, \(K_f\) can be explained as the following, where \(M\) is a metal ion, \(L\) is a ligand, and \(x\) and \(y\) are coefficients: WebThe specific gas constant relates the universal gas constant and the molar mass of a gas (or mixture of gases). The formula is: R s p e c i f c = R M. Where R is the universal gas constant and M is the molar mass of the gas (es) Air is a mixture of gases, so "M" would be the molar mass of the entire mixture.
