I'm not sure ow to do this question.

Calculate the reduction potential of a half-cell consisting of a platinum electrode immersed in a 2.0M Fe2+ and 0.2M Fe3+ solution 25c.

Thanks.
 
The Nernst Equation is given by:

[itex]
E= E_o - \frac{0.059}{n} log \frac{N_1}{N_2}
[/itex]

The above half cell reaction can be written as:

[itex]
Fe^2^+ ------> Fe^3^+ e^_
[/itex]


here n=1 as you can see in the cell reaction.
