For the cell`:` `TI|TI^(o+)(10^(-3)M)||Cu^(2+)(10^(-1)M)|Cu` `E_(cell)` can be increased by `a. ` Decreasing `[Cu^(2+)]." "b.` Decreasing `[TI^(o+)]` `c.` Increasing `[Cu^(2+)] " "d. Increasing by `[TI^(o+)]` |

Answer» Correct Answer - b,c Anode reaction `:` `2Tl(s) rarr 2Tl^(o+)(1^(-3)M)+cancel(2e^(-))` Cathode reaction `:` `Cu^(2+)(10^(-1)M)+cancel(2e^(-)) rarr Cu(s)` `ulbar(2Tl+Cu^(2+)(10^(-1)M)rarr 2 Tl^(o+)(10^(-3)M)+Cu(s))` `E_(cell)=E^(-)._(cell)-(0.059)/(2)log.([Tl^(o+)]^(2))/([Cu^(2+)]^(2))` `=E^(c-)._(cell)-(0.059)/(2)log[Tl^(o+)]^(2)+(0.059)/(2)log[Cu^(2+)]` `E_(cell)` can be increased by decreasing `[Tl^(o+)]` or increasing `[Cu^(2+)]` . |
