`E^(@) (SRP)` of different half cell given `{:(E_(Cu^(2+)//Cu)^(@) =0.34"volt",,,E_(Zn^(2+)//Zn)^(@) =- 0.76"volt"),(E_(Ag^(+)//Ag)^(@) = 0.8"volt",,,E_(Mg^(2+)//Mg)^(@) =- 2.37 "volt"):}` In which cell `Delta^(@)` is most negative:-A. `Zn(s) |Zn^(2+)(1M)||Mg^(2+) (1M)|Mg(s)`B. `Zn(s) |Zn^(2+)(1M)||Ag^(+)(1M)|Ag(s)`C. `Cu(s)|Cu^(2+)(1M)||Ag^(+)(1M)|Ag(s)`D. `Ag(s)|Ag^(+)(1M)||Mg^(2+)(1M)|Mg(s)` |

Answer» Correct Answer - B For (A) and (D) `E_("cell")^(@)=-veimplies Delta G^(@)= +ve` `{:("for"(C),,E_("cell")^(@)= +0.46),("for"(B),,E_("cell")^(@)= +1.56):}` `Delta G^(@)` is most negative for (B). |
