[解題] 國中理化 反應速率與平衡
1.年級：國中二年級
2.科目：CH 4
3.章節：反應速率與平衡
4.題目：A,B,氧 為三種相異物質，混合後產生下列二步驟反應:
(甲)A + 氧氣 → AO2
(乙)B + AO2 → A + BO2
若總反應為(丙) B + O2 → BO2則可以推論催化劑為何?
(A) (甲)
(B) (乙)
(C) O2
(D) AO2
5.想法：
如果假設有一個反應為 A + B → AB (催化劑為C)
則兩個反應為
A + C → AC
AC + B → AB + C (C被還原出來)
所以拿來對照題目的話，應該是A被當作催化劑。
可是沒有這個答案(解答為A)
請問是我觀念錯誤 還是解答有誤呢
