化学?either C or D

化学?either C or D
化学?either C or D

 

化学?either C or D
D啊,不是只有分解反应才需要催化剂的,工业生产、实验室里用催化剂的地方多了.至于一个实验有多种催化剂么,也有很多例子的.比如过氧化氢分解,可以用二氧化锰,三氯化铁,还可以用过氧化氢酶

d

选D
C 2 SO2 +O2 =2SO3 也需要催化剂
D H2O2分解可以用MnO2 或CuO FeCl3 等

DDDD 负责的告诉你 选D

当然是D了。任何种类的反应都可以有催化剂。多种催化剂的组合也是可以的。如双键的加氢反应,不属于分解反应,用Pd-C作催化剂。
