(i) Cu+2HCltoCuCl_(2)+H_(2(g)),[E_(Zn^(2+)//Zn)^(o)=-0.76V] (ii) Zn+2HCltoZnCl_(2)+H_(2(g)),[E_(Zn^(2+)//Zn)^(o)=-0.76V] (iii) Ag+HCltoAgCl+(1)/(2)H_(2(g)),[E_(Ag^(+)//Ag)^(o)=+0.80V] which of the above reactions is feasible

Answer»

(ii)
(i)
(iii)
All the above

Solution :REACTIONS (ii) is FEASIBLE for this `E_(CELL)=+ve` and from `DeltaG=-nFE,DeltaG=-ve`
