A) \[-106.15\text{ }kJ\]
B) \[~-212.30\text{ }kJ\]
C) \[-318.45\text{ }kJ\]
D) \[-424.60\text{ }kJ\]
Correct Answer: B
Solution :
Maximum work done by the cell \[W=-n{{E}^{o}}F\] where, n = number of electrons loss or gain \[{{E}^{o}}\] standard electrode potential of cell. \[F=1F\] or \[96500\text{ }C\] \[\therefore \] \[W=-2\times 1.1\times 96500\] \[\therefore \] \[W=-212300J\] \[\{1000J=1kJ\}\] \[\therefore \] \[W=-212.3kJ\]
