Question
Which of the following will decrease the cell potential for the following reaction:
2Fe3+(aq) + 3Zn(s) 3Zn2+(aq) + 2Fe(s)
Use the reaction Ecell = E°cell (RT/nF)lnQ and consider how each manipulation affects Q and thus affects Ecell
Add zinc solid
Increase concentration of Fe3+ in the solution
Dilute the entire system
Add solid iron to the system
Increase the concentration of zinc ion in solution
Remove water from the entire system
Add zinc solid

Remove water from the entire system
Explanation / Answer
decrease zinc solid
increase Fe3+ concentation
decrease dilution
increase solid iron
decrease
decrease
