Activation energy
Mandarin:
活化能 (huó huà néng)
活化能 (huó huà néng)
Explanation in English Language (EN):
In any chemical reaction, even spontaneous ones, a certain amount of energy is needed to get things started. This energy is the activation energy (Ea). It's like the initial "push" required to get the reactants over an energy barrier so they can transform into products. In polymerization, the activation energy is the energy needed to initiate the formation of the first bond between monomers. Factors like temperature, catalysts, and the specific monomers involved can influence the activation energy of a polymerization reaction.

Explanation in Mandarin (ZH):
在任何化学反应中，即使是自发的反应，也需要一定的能量才能启动。这种能量就是活化能 (Ea)。这就像让反应物越过能量势垒所需的初始“推动力”，以便它们可以转化为产物。在聚合反应中，活化能是引发单体之间第一个键形成所需的能量。温度、催化剂和所涉及的特定单体等因素都会影响聚合反应的活化能。
