1.	Using the standard electrode potentials given in the table predict if the reaction between the following feasible. (a) Fe^(3+)(aq) andI^(-)(aq) (b) Ag^(+)(aq) andCu(s) (c )Fe^3+ (aq) and Cu(s) Ag(s) and Fe^(3+) (aq) (Br_(2))(aq) and Fe^(2+)(aq) (d) Ag(s) and Fe^(3+)(aq) (e) Br_(2)(aq) and fe^(2+)(aq)
Answer» Solution :A particular REACTION can be feasible if e.m.f of the cell based on the `E^(@)` values is positve. KEEPING this in mind,let us predict the feasibility of the reactions. `(a) I^(-)(aq)+Fe^(3+)(aq)rarrFe^(2+)(aq)+1//2I_(2)(g)` `E^(@)_(cell)=0.77-0.54=0.23 V` `(b) Cu(s)+2AG^(+)(aq)rarrCu^(2+)(aq)rarrCu^(2+)(aq)+2Ag(s)` `E^(@)_(cell)=(0.80-0.34)=0.46 V` `(C )3Cu(s)+2Fe^(3+)(aq)rarr3Cu^(2+)(aq)+2Fe(s)` `E^(@)_(cell)=(0.77-0.34)=-0.43 V` `(d) 3Ag(s)+Fe^(3+)(aq)rarr3Ag(+)(aq)+Fe(s)` `E^(@)_(cell)=(0.77-0.80)=-0.03 V` `(e) Fe^(2)(aq)+Br_(2)(g)rarrFe^(3+)(aq)+2 Br^(-)(aq)` `E^(@)_(cell)=1.08-0.77=0.31 V`
