NEET Chemistry Galvanic Cells MCQ Question
Which of the following combinations correctly describe the characteristics and functioning of galvanic cells?
Galvanic cells convert chemical energy to electrical energy; they operate spontaneously; both oxidation and reduction occur in separate compartments.
Galvanic cells require an external voltage to operate; they are non-spontaneous; the anode is positively charged.
Galvanic cells only function during the charging process; they produce energy through electrolysis; the cathode is negatively charged.
Galvanic cells can only use Zn and Cu as electrodes; they generate electrical energy through non-spontaneous reactions; oxidation occurs at the cathode.
Correct Answer
Detailed Explanation
Galvanic cells, such as the Daniell cell, convert chemical energy from spontaneous redox reactions into electrical energy, operate spontaneously, and have oxidation and reduction occurring in separate compartments (anode and cathode).
