EMF series helps in the determination of:
Correct answer: A. Feasibility of reaction
- A. Feasibility of reaction
- B. Mechanism of reaction
- C. Type of reaction
- D. Order of reaction
Explanation
The EMF series helps determine the feasibility of a reaction. Any element higher up in the series can reduce or displace the one lower in the series. For example; Zn + Cu2+ → Zn2+ + Cu Zn2+ + Cu → Zn + Cu2+ With knowledge of the activity series, we can tell that the first reaction is feasible while the second one is not. This is because Cu is higher up in the series than Zn, so it acts as an oxidizing agent. Zn cannot oxidize Cu, so the second reaction is not feasible.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
