2. 一睇Enthalpy cycle 同 Enthalpy level diagram就唔明想做咩, 題目有咩共通點可以記住, 失少d分?
更新1:
Cathode = positive electrode?
更新2:
個website愈睇愈唔明-_-!!!
更新3:
I don't know how to find the enthalpy change using algebraic method.
F5 Chem試前一堆唔明

✔ 最佳答案
1. Positive electrode and positive terminal are the same term.But for Cathode = Positive electrode? It is not really at all.
In chemical cell, it is correct.
In electrolytic cell, it is incorrect because positive electrode is for anode.

Cathode係cation去既地方
cation帶正電荷 所以cathode係陰極 所謂既-ve electrode
