Homework Help: Chemistry

Posted by Aria on Friday, June 21, 2013 at 12:38am.

Using the reaction and the E∘ given below

2Co^3+(aq)+2Cl^−(aq)→2Co^2+(aq)+Cl2(g)

E∘=0.46 V

what is the cell potential at 25 ∘C if the concentration are
[Co^3+]= 0.565M ,
[Co^2+]= 0.554M ,
and [Cl^−]= 0.838M
and the pressure of Cl2 is PCl2= 8.50atm ?

Express your answer numerically in volts.

I know I'm suppose to use the equation

E=E∘-(0.0591/n)logQ

but I'm not really sure how I'm suppose to find the moles of electron (n) and Q. Also, I'm not really sure what I should do with the pressure of Cl2.

Thanks in Advance!
