Effective collision
有效碰撞
Explanation (EN)
A non-elastic collision in which molecules of high kinetic energy overcome repulsion, interpenetrate, and react. [Ch.13 extension: requires both sufficient kinetic energy (E_kin > Ea) and correct molecular orientation (probability p), giving rate = p·f·Z.]
Explanation (ZH)
高动能分子克服排斥、相互穿透并发生反应的非弹性碰撞。【第13章扩展:既需足够动能(E_kin > Ea)又需正确的分子取向(概率 p),故 rate = p·f·Z。】
About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
