Question
Emf for the cell reaction Zn|Zn2+(0.001M)||Zn2+(0.1M)|Zn
Options
A.
ln(0.01)
ln(0.01)B.ln(0.1)
ln(0.1)C.
ln(0.01)
ln(0.01)D.
ln(0.1)
ln(0.1)Solution
Ecell = Eocell - 
lnQ
= Eocell -
= Eocell -
ln (10-2)1/2
= 0 -
ln (10-1)
Ecell = -
ln[0.1]
lnQ= Eocell -
= Eocell -
ln (10-2)1/2= 0 -
ln (10-1)Ecell = -
