E° value of Ni2+/ Ni is –0.25 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.
Answer
(A) Since E ° value for the cell will be positive, redox reaction is feasible.
