If K_(c) for the reaction Cu_((aq))^(2+) + Sn_((aq))^(2+) to Sn_((aq))^(4+) + Cu_((s)) at25^(@) Cis represented as y xx 10^(6) then find the value of y . (Given : E(Cu^(2+) |Cu)^(@) = 0.34 V , E_(Sn^(4+)|Sn^(2+))^(@) = 0.15V )

Answer»


Solution :`E_("CELL")^(0)=(0.059)/(2) log KC , (0.34 - 0.15) = (0.059)/(2) log kc , log kc= (2(0.34-0.15))/(0.059) , kc = 6 xx 10^(6)`
