化学反应的有效碰撞理沦认为:只有当反应物分子具有一最低能量时才能发生化学反应。这一最低能量额定值便是该化学反应的活化能,它是改组反应物化学键和形成生成物化学键的能量保障。而化学反应的过渡态理论则认为:从反应物到生成物,其间有一中间过渡状态,此时反应物的化学键已被破坏,新键初步形成,这一状态下的物质被称作活化络合物。该理论认为,化学反应的活化能主要取决于 Effective collisions of chemical reactions take the view that chemical reactions occur only when reactant molecules have a minimum energy. This minimum energy rating is the activation energy of the chemical reaction, which is the energy guarantee for shuffling chemical reactants and forming chemical bonds of the product. The chemical reaction of the transition state theory is that: from the reactants to the product, there is an intermediate transition between the reactant chemical bond has been destroyed, the new bond initially formed, the state of this material is called activation complexation Things. The theory holds that the activation energy of a chemical reaction mainly depends on it
