δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
The lead (Pb) in the lead storage battery act as an anode
<h3>What is Voltaic Cell?</h3>
A voltaic cell or galvanic cell is an electrochemical cell that uses chemical reactions to produce electrical energy.
<h3>Parts of voltaic cell</h3>
Anode where oxidation occurs Cathode where reduction occurs.
Therefore, Pb acts as anode and PbO2 act as a cathode.
Given,
E° cell = 2.04v
Faraday constant= 96485 C/mol
Moles of electron transferred n= 2
∆G = -nFE°
= -2 × 96485 × 2.04
= 393.658kJ
Thus we concluded that the δg° for the reaction having e° cell = 2.04v. is 393.658kJ.

Basically a covalent bond would have been made based on two atoms so that it can collaboratively set a trace of more electrons. Although there is no atom that is zero which if it had that then it would considerably be a net charge which it is not from this problem. What makes it unique about it is that this attractive force from creating the bond of the electrons that would be purposely activated that are the nuci for constructive used into two atoms.
