[单选题]
Which of the following state1f ;.v qbdqh9gb8l prud:5z. zments are 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 voltaic cells converting chemical energxf3-bo * f ovi;c2l:cgy to electrical energy, whereas, non-spontaneous reactions o ; 3icofg*lv2cxo -fb:ccur in electrolytic cells requiring electrical energy and converting this to chemical energy.
Electrolytic cells typically consist of one reaction vessel containing the aqueous of molten electrolyte. No salt bridge is therefore required.
