On the basis of knowledge of electrochemical series, which reaction is not feasible:
Correct answer: C. Cu + H2SO4 ⟶ CuSO4 + H2
- A. Zn + H2SO4(dil) ⟶ ZnSO4 + H2
- B. F2 + 2KCl ⟶ 2KF + Cl2
- C. Cu + H2SO4 ⟶ CuSO4 + H2
- D. Cl2 + 2KBr ⟶ 2KCl + Br2
Explanation
Copper (Cu) is below hydrogen in the electrochemical series, meaning it cannot displace hydrogen from dilute sulfuric acid (H2SO4). Therefore, this reaction is not feasible.

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.
