Can E("cell")^(@) or Delta(r)G^(@) for c...

Can `E_("cell")^(@)` or `Delta_(r)G^(@)` for cell reaction ever be equal to zero?

Text Solution

Verified by Experts

No (`E_(cell)` an be zero but not `E_(cell)^(@)`). Further, `DeltaG^(@)=-nFE_(cell)^(@)`. As `E_(cell)^(@)ne0`, therefore, `Delta_(r)G^(@)` also cannot be zero.
