Q 2621345221.     (a) What type of a battery is the lead storage battery? Write the anode and the cathode reactions and the overall reaction occurring in a lead storage battery when current is drawn from it.
(b) In the button cell, widely used in watches, the following reaction taken place
`Zn(s) +Ag_2 O_((s)) + H_2O_(l) -> Zn^(2+)(aq) +2Ag (s) +2OH^(-) (aq) `
Determine E0 and `⧍ G^o` for the reaction ( given: `E_(ag^+//Ag)^o =+0.8 V, E _(Zn^(2+)//Zn)^o = -0.76V`)
