1.	Consider the following `E^o` values : `E^o _Fe^(3+)//FE^(2+)o = + 0.77 V` `E_(Sn^(2+)//Sn) =- 0.14 V` Under standard conditions the potential for reaction `Sn(s) +2Fe^(3+) (aq) rarr 2Fe^(2+) (sq) + Sn^(2+) (aq)` is.A. ` 0.63 V`B. ` 1.40 V`C. ` 1.68 V`D. ` 0.91 V`
Answer» Correct Answer - D For ` Sn_(s) + 2Fe_(aq)^(3+) rarr 2 Fe_(aq)^(2+) +Sn_(aq)^(2+)` `E_("cell")^@ =E_(Sn//Sn^(2+))^@ + E_(Fe^(3+)//Fe^(2+))^@ =(0.14) + (0.77)` `E_("cell")^@ =0. 91 V`.
