A varibaleoppositeexternal potential E_("ext") is appliedto thecell Zn|Zn^(2+)(1M)|Cu^(2+)(1M)|Cu of potential1.1 VwhenE_("ext")lt 1.1 V andE_("ext") gt 1.1 Vrespecitively electrons flowfrom

Answer»

cathodeto ANODE in both cases
cathode to anode and anode to cathode
anode to cathode and cathode to anode
anode to cathode in both cases

SOLUTION :Forthe daniell CELL
`E_("cell") = 0.34 -(-0.76) = 1.10 V`
when`E_("ext") LT 1.10 V`electronsflowformcathode to anodein externalcircuit
when `E_("ext")gt 1.10 V` electron flowform cathode to anodein externalcircuit (reverse reaction )
