1.	A button cell used in watches function as following `Zn(s)+Ag_(2)O(s)+H_(2)O(l)hArr2Ag(s)+Zn^(2+)(aq)+2OH^(-)(aq)` if half cell potential are `Zn^(2+)(aq)+2e^(-)toZn(s),` `Ag_(2)O(s)+H_(2)O(l)+2e^(-)to2Ag(s)+2OH^(-)(aq),E^(@)=0.34V ` The cell potential will beA. 1.34VB. 1.10VC. 0.42VD. 0.84V
Answer» Correct Answer - B ]`Zn^(2+)(aq)+2e^(-)toZn(s),E^(o)=-0.76V` `Ag_(2)O(s)+H_(2)O(l)+2e^(-)to2Ag(s)+2OH^(-)(aq),E^(o)=0.34V` `Zn(s)+Ag_(2)O(s)+H_(2)O(l)+2e^(-)to2Ag(s)+2OH^(-)(aq)` `+2OH^(-)(aq),E_(cell)=?` `E_(cell)^(o)=(E_(R.P.)^(o))_("cathode")-(E_(R.P.)^(o))_("anode")` `E_(cell)^(o)=0.34(-0.76)=1.10V` `E_(cell)=E_(cell)^(o)=1.10V`
