The lead-containing reactant(s) consumed during recharging of a lead-acid battery is/are ________. The lead-containing reactant(
s) consumed during recharging of a lead-acid battery is/are ________. PbSO4 (s) only Pb (s) only PbO2 (s) only both PbO2 (s) and PbSO4 (s) both Pb (s) and PbO2 (s)
Answer: The lead-containing reactant(s) consumed during recharging of a lead-acid battery is
Explanation:
In lead acid battery, the anode is made up of lead and undergoes oxidation during discharging and cathode is made up of lead oxide and acts as cathode during discharging. The electrolyte used is dilute .
Charging:
Cathode : reduction :
Anode: oxidation :
Overall reaction :
The lead-containing reactant(s) consumed during recharging of a lead-acid battery is
A second order reaction varies with the square of the concentration of the reactant. Therefore, halving the concentration will reduce the rate of reaction by a factor of 4. The answer is E.
