Answer:
The over all reaction :
The standard cell potential of the reaction is 0,.897 Volts.
Explanation:
Reduction at cathode :
..[1]

Reduction potential of
to 
Oxidation at anode:
.[2]

Reduction potential of
to 
To calculate the
of the reaction, we use the equation:

Putting values in above equation, we get:


The over all reaction : 2 × [1] + [2]
The standard cell potential of the reaction is 0,.897 Volts.
