三是傳統考試的重點,講了化學反應中的電子轉移和能量變化。Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons.
四是抽象知識的難點,講了化學反應的機理和化學反應速率。
Rates of chemical reactions are determined by details of the molecular collisions.
五是承上啟下的關鍵,講了物質能量的變化和熱力學原理。
The laws of thermodynamics describe the essential role of energy andexplain and predict the direction of changes in matter.
六是計算考察的必考,講了化學平衡以及相關能量變化。
Any bond or intermolecular attraction that can be formed can be broken.These two processes are in a dynamic competition, sensitive to initialconditions and external perturbations.
不難看出,改革后的AP化學更加注重圖像問題,希望學生能用微觀粒子描述物質的性質,反應和變化
總之不管題型如何改變,所考的化學知識仍是教材上的內容,大家平時不僅要學好基礎知識,更要懂得融會貫通,舉一反三,這樣即便題目再變,也能從容應對!
