Expert Solution
Introduction
Calculations
The given reaction is as follows:
For the given reaction, the half-reduction reaction (at cathode) can be written as follows:
The standard reduction potential for the above reaction is 0.536 V.
The half-reduction reaction (at cathode) can be written as follows:
The standard reduction potential for the above reaction is 0.159 V.
Now, substitute the values in the expression (I).
The standard free energy is calculated by using the relation shown below.
Here,
The number of electrons transfer in the reaction is “n”.
The Faraday’s constant is “F” (96500 C/mol).
