What is the calculated value of the cell potential at 298K for an electrochemical cell with the following reaction, when the Cl2 pressure is 1.14 atm, the Cl- concentration is 2.62×10-3M, and the Sn2+ concentration is 7.76×10-4M ?
Cl2(g) + Sn(s)=2Cl-(aq) + Sn2+(aq)

1 Answer
Explanation:
The standard reduction potentials for each half-reaction are:
Calculate the standard cell potential
You want
Your standard cell is not spontaneous as written.
Calculate the cell potential
You have non-standard pressure and concentrations, so you must use the Nernst equation:
#color(blue)(bar(ul(|color(white)(a/a)E_text(cell) = E_text(cell)^° - (RT)/(nF)lnQcolor(white)(a/a)|)))" "#
Your cell is not spontaneous as written.
