The reaction in Galvanic Cell is:
Correct answer: A. Spontaneous
- A. Spontaneous
- B. Non-spontaneous
- C. Irreversible
- D. Endothermic
Explanation
The correct option is A. The galvanic cell acts as a device that simultaneously undergoes oxidation and reduction reactions. These reactions are used to convert chemical energy into electrical energy. Ideally, the battery will include two electrodes. One of these electrodes, the cathode, will be the positively charged electrode, and the other will be the anode, the negatively charged electrode. During the oxidation-reduction reaction, the galvanic cell uses the energy transfer between electrons to convert chemical energy into electrical energy. Therefore, the reaction in the galvanic battery does not provide external energy, which is why we can say that the reaction in the galvanic battery is inherently spontaneous.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
