Chemistry Question on Nernst Equation

The anodic half-cell of lead-acid battery is recharged unsing electricity of 0.050.05 Faraday. The amount of PbSO4 {PbSO_4} electrolyzed in g during the process in : (Molar mass of PbSO4=303  g  mol−1 {PbSO_4 = 303 \; g \; mol^{-1}})

A

22.8

B

15.2

C

7.6

D

11.4

Answer

15.2

Explanation

Solution

(A) {\underset{\text{ 0.05/2 mole}}{ { PbSO4(s) }}+2OH−−>PbO2+H2SO4++ 2OH^{-} -> PbO_2 + H2SO4 +\underset{\text{ 0.05F}}{ { 2e^{-}}} } (C) {\underset{\text{ 0.05/2 mole 0.05 F}}{ { PbSO4 + 2e^{-}}} + 2H^{+} -> Pb(s) + H2SO4} nT(PbSO4)=0.05 mole{ n_{T} (PbSO_4) = 0.05 \, mole} mPbSO4=0.05×303=15.2  gm {m_{PbSO_{4}} = 0.05 \times 303 = 15.2 \; gm }
