Identify the overall oxidation reaction that occurs in a lead storage cell during discharge.

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: In equation $\Delta_r G = -nFE_{\text{cell}}$,the value of $\Delta_r G$ depends on $n$.
Reason $R$: $E_{\text{cell}}$ is an intensive property and $\Delta_r G$ is an extensive property.
In the light of the above statements,choose the correct answer from the options given below:

Which of the following reactions is possible at the anode?

Why is a finely divided particle layer of $Pt$ and $Pd$ provided on the electrodes of a fuel cell?

In the button cells widely used in watches and other devices,the following reaction takes place:
$Zn_{(s)} + Ag_2O_{(s)} + H_2O_{(l)} \rightarrow Zn^{2+}_{(aq)} + 2Ag_{(s)} + 2OH^{-}_{(aq)}$
Determine $\Delta_r G^\Theta$ and $E^\Theta$ for the reaction.

Give true $(T)$ and false $(F)$ for following statements :
$(1)$ There is no difference between the galvanic and the electrolytic cell.
$(2)$ In electrolytic cell,anode of galvanic cell is cathode and cathodes are anode.
$(3)$ The flow of current and electron in electrolytic cell is opposite to the galvanic cell.
$(4)$ When $2.0 \ V$ external current in the opposite direction is passed through the Daniell cell,in such condition there is no effect on Daniell cell.
