[单选题]
Which of the following statements fe7zljw6t vlk* o)k szsjm-po;r8 rbc2l:./; areu.kdp-4bm*5vg8e pb o 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 coj81),j lg k xbq:myzf;nverting chemical energy to electrical energy, whereas, non-spontaneous reactions occur 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 elec; j qjm:ygx8 1kzfbl,)trolyte. No salt bridge is therefore required.
