In which cell is the free energy of a chemical reaction directly converted into electricity?

Consider a cell given below $Cu \,|\, Cu^{2+} \,|\, | \, Cl^{-} \,|\, Cl_2$,$Pt$. Write the reactions that occur at anode and cathode.

Given the data at $25\, ^oC$:
$Ag + I^{-} \rightarrow AgI + e^-$,$E^o = 0.152\, V$
$Ag \rightarrow Ag^{+} + e^-$,$E^o = -0.800\, V$
What is the value of $\log K_{sp}$ for $AgI$? $(2.303\, RT/F = 0.059\, V)$

Which of the following reactions is possible at the anode?

$A$ moving coil galvanometer has $150$ equal divisions. Its current sensitivity is $10 \text{ divisions per milliampere}$ and voltage sensitivity is $2 \text{ divisions per millivolt}$. In order that each division reads $1 \text{ V}$,the resistance in ohms needed to be connected in series with the coil will be

What is the molar conductivity of $CH_3-CO_2H$ at infinite dilution?
Given that,
$\wedge_{m}^{o}(CH_3-CO_2)_2Ba = x_1 \ S \ cm^2 \ mol^{-1}$
$\wedge_{m}^{o}(BaCl_2) = x_2 \ S \ cm^2 \ mol^{-1}$
$\wedge_{m}^{o}(HCl) = x_3 \ S \ cm^2 \ mol^{-1}$
