NEET Chemistry Electrode Potential MCQ Question
E° value of Ni²⁺/Ni i.25 V and Ag⁺/Ag is +0.80 V. If a cell is made by taking the two electrodes what is the feasibility of the reaction?
Since E° value for the cell will be positive, redox reaction is feasible.
Since E° value for the cell will be negative, redox reaction is not feasible.
Ni cannot reduce Ag⁺ to Ag hence reaction is not feasible.
Ag can reduce Ni²⁺ to Ni hence reaction is feasible.
Correct Answer
Detailed Explanation
The cell potential is positive (0.⁸⁰⁻ (-0.25) = 1.05 V), indicating a feasible redox reaction.
