What does a negative cell voltage value for a reaction means?
Correct answer: C. Reaction is non-spontaneous
- A. None of these
- B. Reaction is exothermic
- C. Reaction is non-spontaneous
- D. Reaction is spontaneous
Explanation
The voltage value for a reaction is given by: E° = E° cathode - E° anode where E° is the cell voltage value for a reaction. If E° is positive, the reaction is spontaneous or exothermic. If E° is negative, the reaction is non-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.
