So the above equation is the net reaction.

By the Nernst equation:

0.0592 (0.044)

D

2 (4.4)

= (-0.296) (-2.0)

= 0.0592 V

which is positive.

Let us assume the cell:-

Mg | Mg

In this case the reaction is as follows:-

Mg + 2 Ag

Now Applying the Nernst equation

0.0592 (Product) Mg

D

2 (Reactant) [Ag

Now we need to multiply the equation of reaction by 2, we will find the following equation:-

2 (Mg + 2 Ag

2 Mg+ 4 Ag+ = 2 Mg+ + 4 Ag

Now we can see that there are 4 electrons intricate in this equation and hence

0.0592 [Mg

D

4 [Ag

This equation can further be simplified as below:-

0.0592 [Mg

D

2 [Ag

Hence we see that the result remains unchanged.
