Zinc/silver oxide cell is used in hearing aids and electric watches. The following reactions occur :
`Zn(s) to Zn^(2+)(aq)+2e^(-) , E_(Zn^(2+)//Zn)^(@)=-0.76V`
`Ag_(2)O+H_(2)O+2e^(-) to2Ag+2OH^(-),E_(Ag^(+)//Ag)^(@)=0.344" V"`
Calculate (i) Standard potential of the cell (ii) Standard Gibbs energy.
