Consider the following ` E^@` values . `E_(Fe^(3+)//Fe^(2+)^@ = + 0.77

1.	Consider the following ` E^@` values . `E_(Fe^(3+)//Fe^(2+)^@ = + 0.77 V`, `E_(Sn^(2+)//Sn)^@=- 15. V` The `E_(cell)^@` for the reaction , `Sn (s) + 2Fe_(aq)^(3+) rarr 2 Fe_(aq.)^(2+) + Sn_(aq.)^(2+) is :A. ` 0.63 V`B. `1. 40 V`C. ` 0. 91 V`D. ` 1. 668 V`
Answer» Correct Answer - C `E_(cell)^@ =E(OPSn//Sn^(2+)) +E_(Fe^(2+)^@//Fe^(2+)`. ` =0.14 + 0.77 = 0. 91 V`.
