The standard oxidation potential `E^@` for the half cell reaction are `Zn rarr Zn^(2+) + 2e^-` `E^@=+ 0.76 V ` `Fe rarr Fe^(2+) + 2e^-` `E^@=+ 0.41 V ` EMF of the cell rection is `Zn+Fe^(2+) rarr Zn^(2+)+Fe `A. `1.17 ` VB. `0.35` VC. `-1.17 V `D. `-0.35` V

Answer» Correct Answer - B
Here oxidation potentials are given
`E_(cell)^(@) = E_("OX (LHS)")^(@) - E_("OX (RHS)")^(@)`
The cell is -
Anode (LHS) `to` Higher SOP
Cathode (RHS) `to` Lower SOP
`E_(cell)^(@) = 0.76 - 0.41 = 0.35 V `
