[单选题]
Which of the following statements arey.wce(w mh2t py k1,b1*hnhd (/;,3fs hcofkq correct?
I.Voltaic cells convert chemical energy into electrical energy
II.Electrolytic cells convert electrical energy into chemical energy
III.Electrolytic cells require a salt bridge
A. I and II only
B. I and III only
C. II and III only
D. I, II, and III
参考答案: A
本题详细解析:
Spontaneous reactions occur in v:vo;3olhn ; e)lms7 nzudxe/7 oltaic cells converting chemical energy to electrical energy, whereas, non-spontaneous reactions occur in electrolytic cells requiring electrical energy and converting this to chemico7x m l :3dznenvo;e;luhs7/ )al energy.
Electrolytic cells typically consist of one reaction vessel containing the aqueous of molten electrolyte. No salt bridge is therefore required.
