\[Zn(s)+C{{u}^{2+}}(aq)\to Z{{n}^{2+}}(aq)+Cu(s),\] |
\[{{E}^{o}}=2\,V\,at\,298K\] |
(Faraday's constant, \[F=96000\,C\,mo{{l}^{-1}}\]) |
A) -384
B) -192
C) 192
D) 384
Correct Answer: A
Solution :
\[\Delta {{G}^{o}}=-nF{{E}^{o}}_{cell}\] \[=2\times 96000\times 2\] \[=384000\text{ }J\] \[=384\text{ }kJ\] \[\therefore \] Ans. is [a]You need to login to perform this action.
