Please do it fast n 4. During discharging oflead-storage acid battery following reaction takes place: Pb0: (S) + 21120 If 2.5 amp ofcurrent is drawn for 965 minutes, H, SO. consumed is:

Dear Student,


We know that, Q = It    =(2.5 A) ×(965×60) s    =144750 CNow, reaction taking place are :Anode : Pb(s) + SO42- (aq) PbSO4(s) + 2e-Cathode : PbO2(s) + 4H+(aq) + SO42-(aq) +2e-  PbSO4(s) + 2H2O(l)So, 2 mol of e- needs 2 mol of H2SO4or, 2×96500 C of e- needs 2 mol of H2SO4Therefore, 144750 C of e- needs 22×96500×144750=1.5 mol of H2SO4
