Dear Student

Electrolysis of H2SO4 in water gives At Cathode: 4H+ + 4e-→ 2H2At Anode: 2H2O → 4H+ + O2 + 4e- (for 4e- , 4 F is used)But for same passage of current, there will be two moles of H2 and 1 mole of O2
From this we can say if we use 2 F , 1 mole of H2 and 0
5 mole of O2Since, 1 mole is equal to 22
4 L , thus 1
5 moles of gases in total will be ( 22
4 + 11 2 )= 33 6 LOption 3
