Crystal field activation energy
WebCrystal field theory, which assumes that metal–ligand interactions are only electrostatic in nature, explains many important properties of transition-metal complexes, including … WebMay 7, 2024 · The value of E determines the temperature sensitivity of the process rate. The larger the activation energy, the stronger the process rate changes per the same change in temperature. As such, the value of E determines another quantity called the temperature coefficient of the rate, Θ.This quantity has been introduced by van’ t Hoff and is defined …
