B:错误
答案: 错误

12、 The goal of green chemistry is to eliminate the potential of pollution before it occurs.

A:正确
B:错误
答案: 正确

13、 One of the obvious effect of catalysis to facilitate the reaction is to minimize the activation energy (energy costs), and thus reduce the reaction temperature.

A:正确
B:错误
答案: 正确

14、 Traditional pollution treatment can provide a permanent cure.

A:正确
B:错误
答案: 错误

15、 Chemical reaction with 100% atom utilization has two characteristics. The reactants could be fully utilized, and the resource could be most possibly used economically. The waste could be minimized.

A:正确

B:错误

答案: 正确
