1. For the reaction 2Co3+(aq)+2Cl−(aq)→2Co2+(aq)+Cl2(g).
E∘=0.483 V what is the cell potential at 25 ∘C if the
concentrations are [Co3+]= 3.00×10−2 M , [Co2+]= 0.675 M , and
[Cl−]= 0.862 M , and the pressure of Cl2 is PCl2= 4.60 atm ?
Express your answer with the appropriate units.
2. Consider the reaction: Mg(s)+Fe2+(aq)→Mg2+(aq)+Fe(s) at
49 ∘C ,
where [Fe2+]=3.30 M and [Mg2+]= 0.310 M
2a. What is the value for the reaction quotient, Q,
for the cell?
