Correct Answer - A.Feasible b.Feasible c.Notfeasible d.Notfeasible e.Feasible A reaction is feasible if the EMF of the cell reaction is +ve a.Fe3+(aq)+Ic-(aq)→Fe2+(aq)+ 1 2 I2 Pt,I2|Ic-(aq)||Fe3+(aq)|Fe2+(aq)∣Pt ∴E c- cell =E(Fe3+^(c-)∣Fe2+)-E c- (I2∣Ic-) =0.77-0.54=0.23V(Feasible ) b. Ag⊕=Cu→Ag(s)+Cu2+(aq) i.e., Cu|Cu2+(aq)||Ag⊕(aq)|Ag =0.80-0.34=0.46V(Feasible ) c. Fe3+(aq)+Brc-(aq)→Fe2+(aq)+ 1 2 Br2, E c- cell =0.77-1.09=-0.32V(not feasible) d.Ag(s)+Fe3+(aq)→Ag⊕(aq)+Fe2+(aq), E c- cell =0.77-0.80=-0.30V(not feasible) e. 1 2 Br2(aq)+Fe3+(aq)→Brc-+Fe3+, E c- cell =1.09-0.77=0.32V(feasib≤)
