Answer:
The only thing that will not affect the potential is the adition of solid Sn.
Explanation:
The potencial of a cell is linked to the concentration of the substances involved in the reactions by the equation of Nernst. So a change of one of them would change the cell potential.
[tex]E=E^{\circ}-\frac{R*T}{n*F}*ln(Keq)[/tex]
The Keq for this reaction is:
[tex]K_{eq}=\frac{[Sn^{2+}]*[H_2]}{[H^+]}[/tex]
Sn is not included because it's in solid state.
As can be seen, changing the concentrations of H2 (increasing the pressure), H+ (lowering the pH) or Sn2+ will affect the potential.
The only thing that will not affect it is the adition of solid Sn.
Based on the equilibrium constant equation, addition of Sn will not affect cell potential.
Cell potential refers to the potential difference that exists between two points in an electrochemical cell.
The Nerst equation shows the relationship between the cell potential and the concentration of the substances involved in the reactions.
[tex]E=E^{\circ}-\frac{R*T}{n*F}*ln(Keq)E=E
∘
−
n∗F
R∗T
∗ln(Keq)[/tex]
Any change of one values results in a change in the cell potential.
The equilibrium constant for this reaction is given as follows:
[tex]K_{eq}=\frac{[Sn^{2+}]*[H_2]}{[H^+]}[/tex]
Based on equilibrium constant equation, changing the amount of Sn will not affect cell potential since it is not included in the equilibrium constant equation.
Therefore, addition of Sn will not affect cell potential.
