Ea meaning in chem
WebNov 14, 2024 · Definition of electron affinity. Electron affinity is the affinity of an element to an electron. This is measured by the energy released when an element in its gaseous state accepts an electron to form an anion. So this is an exothermic reaction. They are expressed in KJ mol -1. Since one, two or more electrons can be added to form an anion ... WebConsidering a chemical reaction at two different temperatures T 1 and T 2, whose corresponding rate constants are k 1 and k 2 respectively, the logarithmic form of the Arrhenius equation is: ln k 1 = ln (A) – E a /RT …
