If `e_(Fe^(2+) //Fe)^@ =- 0. 44 1V`. And `E_(Fe^(3+)//Fe^(2+))^(o) = 0

1.	If `e_(Fe^(2+) //Fe)^@ =- 0. 44 1V`. And `E_(Fe^(3+)//Fe^(2+))^(o) = 0. 771 V`. The standard emf of the reaction ` Fe +2 Fe^(3+) rarr 3Fe^(2+)` will be .A. `1.212 V`B. `0.111 V`C. `0.330 V`D. `1.653 V`
Answer» Correct Answer - A `E_("cell") = E_(Fe//Fe^(2+))^(@) + E_(Fe^(3+)//Fe^(2+))^(@)` `= 0.441 + 0.771 = 1.212 V`
