Find the value of AG^(@) at 25^(@)C for ...

Find the value of `AG^(@)` at `25^(@)C` for the following electrochemical cell.
`Cu|Cu^(2+)(1M)||Ag^(+)(1M)|Ag`
`[Ec_(u)=+0.34V, E_(Ag)^(@)=+0.8V]`
`F=96487C`

Text Solution

Verified by Experts

`E_("cell")^(@)=E_("cell")-E_("anode")=0.8-0.34=0.46V`
`DeltaG^(@)=-nFE_("cell")^(@)=-2xx96500xx0.46=-88780J`
