課程概覧

Rate of reaction 係 part II 嘅 topic,基本上年年都會出,而且佢同 elective 嘅 industrial chemistry 係會有好大嘅關連,同埋最重要嘅係呢課嘅概念係一啲都唔深,直頭係淺添,所以係超抵讀。

上完呢個課程之後,大家就會學:

  1. 基於 reaction 嘅特性,揀唔同嘅方法去 monitor 一個 reaction 嘅 progress。
  2. 用 rate curve 去表達唔同嘅 reacting species 响 reaction 進行期間,concentration 嘅變化。而且亦都識點樣從 rate curve,graphically 去搵出 initial rate,instantaneous rate 同埋 average rate。
  3. 點樣去設計一個 fair experiment 去揾出唔同嘅 conditions,例如 concentration,temperature,solid reactant 嘅 surface area 同埋 catalyst 對 rate of reaction 嘅影響。
  4. 利用 collision theory,qualitatively 去解釋 concentration,temperature 同 surface area 點樣影響 rate if reaction。
  5. Enzyme 係一種 biochemical catalyst。
  6. 响同一個 condition 底下,例如响 room temperature 同 pressure 底下, 所有嘅 gas 嘅 molar volume 都等如 24 dm3。而且仲會學識計有關 molar volume 嘅 mole calculation。

【深度學習】系列啱邊種學生報讀?

【Chem-Animax】系列嘅課程可以幫你掌握到每個課題嘅基本概念。但如果你想更深入了解每個課題嘅要點同答題方針,咁就可以報讀【深度學習】系列嘅課程!呢個系列係專為一啲願意付出時間、心機去為未來前途打拼嘅同學而設。

响課程嘅數小時𥚃面,我會同你一齊深度探討每一個 topic 嘅要點、答題技巧,從零開始帶領住你一步一步掌握所有DSE要識嘅概念!

課程附有一份精美筆記,筆記內容除咗用精簡嘅文字表達之外,仲附有大量 infographics 圖畫,可以幫你加強理解同記憶。加上適量嘅例題、習題加以解明,亦能提升你嘅答題技巧。有咗概念加上技巧,同學應付考試,就自然得心應手。

關於導師

Winter Sir 自從取得化學哲學碩士MPhil 之後,便加入教育行列。在一所英文中學任教了超過二十年。任化學科科主任亦超過十年。曾任公開考試閲卷員。
但......因為教得太耐,越教越覺得悶,越冇動力!不安於現狀嘅我,決定响五年前,開始拍以動畫形式進行嘅教學片。懶係雄心壯志,誓要將整個DSE 課程拍成動畫放上 YouTube,可以俾學生隨時隨地睇。經過幾年嘅努力,我所設立嘅 YouTube Channel chemchemday 訂閱人數已經超越4300。所拍嘅短片亦超過666 條。
近年接觸咗翻轉教學 flipped learning 之後,更加成為 flipped learning 嘅狂熱份子,燃燒返我對教育嘅熱誠,唔想再做教育界嘅老海鮮!希望可以將翻轉教學呢一種教學模式推廣到其他學校。

Chem Chem Day video is in high quality, it helps students to clear concept and master the skills to strive for a better results in DSE Chemistry. It is worthwhile to attend all his classes. Chemistry will help us solve many future problems, including sustainable energy and food production, managing our environment, providing safe drinking water and promoting human and environmental health

語速正常,課室講解亦十分清晰。老師在課堂中運用了不同的例子來作比喻,令 Concept 變得清晰易明。十分好!想清 Concept 嘅建議購買。

第28和29的內容並沒有講及但又沒有提供答案,使我有一點困惑
但其他都非常清晰易明
