When a lead storage battery is discharged:

(a) What type of a battery is the lead storage battery ? Write the anode and the cathode reactions and the overall occuring in a lead storage battery when current is drawn from it. (b) In the buttom cell, widely used in watches the following reaction take place Zn_((s)) + Ag_(2)O_((l)) rarr Zn^(2+)(aq) + 2Ag_((s)) + 2OH_((aq))^(-) . Determine E^(@) and DeltaG^(@) for the reaction. (given : E_(Ag^(+)//Ag)^(@) = +0.80 V , E_(Zn^(2+)//Zn)^(@) = - 0.76 V)

What type of a battery is lead storage battery? Write the anode and cathode reactions and the overall cell reaction occurring in the operation of a lead storage battery. (b) Calucluate the potential for half-cell containing. 0.10 M K_(2)Cr_(2)O_(7)(aq), 0.20 M Cr^(3+) (aq) and 1.0 xx 10^(-4) M H^(+) (aq) The half -cell reaction is Cr_(2)O_(7)^(2-) (aq) + 4H^(+) (aq) + 6 e^(-) to 2 Cr^(3+) (aq) + 7H_(2)O(l) and the standard electron potential is given as E^(o) = 1.33V .

(a) What type of a cell is the lead storage battery ? Write the anode and the cathode reactions and the overall reaction occuring in a lead storage battery while operating . (b) A voltaic cell is set up at 25^(@)C with the half-cells , Al|Al^(3+) (0.001M) and Ni| Ni^(2+) (0.50 M) . Write the equation for the reaction that occurs when the cell generates an electric current and determine the cell potential. (Given : E_(Ni^(2+)|Ni)^(@) = -0.25 V , E_(Al^(3+)|Al)^(@) = -1.66V ).
