通常而言,IBDP 化學被視作一門比較難的學科。但對于一些小伙伴而言,IB化學卻并不那么難。這兩者并不矛盾。今天帶著大家一起看一道IBDP化學課程的真題(HIGHER LEVEL PAPER 2)。這道題取自于IBDP chemistry specimen paper。不多說,直接上題。
題目1:One of the main constituents of acid deposition is sulfuric acid. This acid is formed from the sulfur dioxide pollutant.A mechanism proposed for its formation is:

(b) Consider the following equilibrium between the two oxides of sulfur, sulfur dioxide and sulfur trioxide:

題目難度:簡單。
考點分析:考查position of equilibrium shift
題目分析:升高溫度朝著吸熱的方向移動,升高壓強朝著分子數減少的方向移動,加催化劑不影響。
正確答案:

題目2:One of the main constituents of acid deposition is sulfuric acid. This acid is formed from the sulfur dioxide pollutant.A mechanism proposed for its formation is:

(a) State what the symbol (·) represents in the species shown in this mechanism. [1]
題目難度:簡單。
考點分析:考查free radical
題目分析:點就代表radical,也就是未成對的電子。
正確答案:radical / unpaired electron
