In the button cells widely used in watches and other devices the following reaction takes place:
`Zn(s)+Ag_(2)O(l)toZn^(2+)(aq)+2Ag(s)+2OH^(-)(aq)`
Determine `Delta_(r)G^(Ө)` and `E^(Ө)` for the reaction.

Text Solution

Verified by Experts

The correct Answer is:
`a. 1.104V` , `b. -2.13xx10^(5)J`
`a.` `E_(cell)^(c-)=E_((Ag_(2)O|Ag)"red")^(c-)-E_((Zn^(2+)|Zn)"red")^(c-)`
`=0.344-(-0.76)=1.104V`
`b. Delta_(r)G^(c-)=-nFE^(c-).(n_(cell)=2)`
`-2xx96500xx1.104J`
`=-2.13xx10^(5)J`
