The measured e.m.f. at 25^(@)C for the cell reaction Zn(s)+Cu^(2+)(1.0M)hArrCu(s)+Zn^(2+)(0.1M) is 1.3 volt. Calculate E^(@) for the cell reaction.

Answer»


SOLUTION :`E_(CELL)=E_(cell)^(@)-(0.0591)/(N)"log"([Zn^(2+)])/([CU^(2+)]),1.3=E_(cell)^(@)-(0.0591)/(2)"log"(0.1)/(0.1)" or "E_(cell)^(@)=1.27045V`
