<u>Answer:</u> The cell voltage of the given chemical reaction is 2.74 V
<u>Explanation:</u>
For the given chemical reaction:
Here, gold is getting reduced because it is gaining electrons and nickel is getting oxidized because it is loosing electrons.
<u>Oxidation half reaction:</u>
<u>Reduction half reaction:</u>
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
To calculate the EMF of the cell, we use the Nernst equation, which is:
where,
= electrode potential of the cell = ?V
= standard electrode potential of the cell = +2.76 V
n = number of electrons exchanged = 2
Putting values in above equation, we get:
Hence, the cell voltage of the given chemical reaction is 2.74 V
