Write Nernst equation for the reaction :
`2Cr(s)+3Fe^(2+)(aq)to2Cr^(3+)(aq)+3Fe(s)`

Text Solution

Verified by Experts

`{:(2Cr(s)to2Cr^(3+)(aq)+6e),(3Fe^(2+)(aq)+6eto3Fe(s)),(_),(2Cr(s)+3Fe^(2+)(aq)to2Cr^(3+)(aq)+3Fe(s)),(_):}`
Nernst equation is `E_("cell")=E_("cell")^(@)+(0.0591)/(6)log""([Fe^(2+)]^(3))/([Cr^(3+)]^(2))`
`=(n=6)`
