(b) The `E^(theta)` values corresponding to the following two reduction electrode processes are :
(i) `Cu^(+)//Cu=0.52V" (ii) Cu^(2+)//Cu^(+)=0.16V`
Formulate the galvanic cell for their combination. Calculate the cell potential and `DeltaG^(@)` for the cell reaction.

Text Solution

Verified by Experts

`Cu^(2+)+e^(-)rarrCu`
`Cu^(+)rarr Cu^(2+)+e^(-)`
`"Overall cell reaction : "2Cu^(+)rarrCu+Cu^(2+)`
`Cu^(+)//Cu^(2+)||Cu^(+)//Cu`
`E_("cell")^(theta)=0.52-0.16=0.36V`
`DeltaG^(@)=-mFE_("cell")^(theta)`
`=-1xx96500xx0.36`
`=-"24740 J mol"^(-1)`
