A) \[[Z{{n}^{2+}}]\] should be increased
B) \[[Z{{n}^{2+}}]\] should be decreased
C) \[[C{{l}^{-}}]\]should be decreased
D) \[{{P}_{C{{l}_{2}}}}\]should be decreased
Correct Answer: B
Solution :
According to nernst's equation \[E_{Cell}^{{}}=E_{Cell}^{0}-\frac{nRT}{F}\log \frac{{{c}_{1}}}{{{c}_{2}}}\] For \[Z{{n}_{(s)}}+C{{l}_{2(1\ atm)}}\to Z{{n}^{2+}}+2C{{l}^{-}}\] \[{{c}_{1}}=[Z{{n}^{2+}}]\] and \[{{c}_{2}}=[C{{l}^{-}}]\] Hence to increase E, \[{{c}_{1}}\] should be decreased and \[{{c}_{2}}\] should be increased is \[[Z{{n}^{2+}}]\] should be decreased and Cl should be increased.You need to login to perform this action.
