The correct option for the
Concept introduction:
For a chemical species, reduction potential is defined as the tendency to gain an electron and get reduced.
The potential of each redox couple under the standard state (concentration = 1 M, T = 298 K and P = 1 atm) for all regents is said to be the standard reduction potential,
Answer to Problem 18STP
The correct option is (c) as
Explanation of Solution
The two half-reactions and their reduction potential values are:
The higher value of reduction potential indicates that it has a greater tendency to gain electron and reduce then the other species which has lower reduction potential. Since, the reduction potential of zinc is greater than lithium so, the zinc will undergo reduction and lithium will undergo oxidationfor the given electrochemical cell.
The reduction reaction will take place at cathode and oxidation at anode. The half-cell reactions are:
The cell potential is determined by difference between the reduction potential of two electrodes (cathode and anode). The formula is:
The value of
Hence, the correct option is (c) as
