enthalpy cycle 唔係好普通咩
幾時變咗係伏

因為好多人學左另一個快d既approach

應該話 HKEA咁多年從來無考指明用某某方法做既enthalpy
咁有一部分老師會教學生用其他方法做而唔用cycle
估唔到佢今年硬性要畫

即使我中學老師講左好多年cycle 唔會出 但要識畫 佢今年都o左嘴

P2 35/40
P1最少幾多有*
係咪P1一分等於P2兩分?

係咪+226 kJmol -1

因為好多人學左另一個快d既approach

反而我以為大家會掛住計數，唔識點解做唔到formation of C2H2同hess's law definition 不過無人討論，睇黎大家都識
等我仲臨考一日先背左幾個definition

Hess law definition
我寫左The total enthalpy of reaction are constant 😂😂

想知快approach 是乜

想問elective in chem
比左個圖問order of reaction
係咩order

我覺得答side product is wrong if pp recite marking

Con against time
Decrease linearly
U think ?

我寫first order
但見到kelvin lau IG 打話咩 zeroth order
仲話mock出過 應該要識

Zeroth
Concentration of A decreases linearly with time
