Answer» Correct Answer - A`to`p,q,s ; B`to`r,s ; C`to`p,q ; D`to`p,q,s,t `E_("cell")=-0.0591/2"log"C/(2C)=8.89xx10^(-3)` Spontaneous, cell works, conc cell `E_("cell")=-0.0591 "log"1/0.5 =- 0.0591` Non spontaneous cell will not work conc cell `E_("cell")=-0.0591/2"log"0.01/0.1^2-0.74+0.8=0.06` Spontaneous cell works `E_("cell")=-0.0591/1"log"(Cl^-)/(K_(sp))-0.0591/1"log"1/([Ag^+])` `=0.0591/2"log"(0.1xx0.1)/(K_(sp(AgCl))=+ve` Spontaneous cell works conc cell For anode `Ag(s)+Cl^(-)(aq)toAgCl(s)+e^-` |
