Explanation:
Half-Cell Reaction:
The given half-cell reaction is Al3+ + 3e- → Al. This reaction involves the reduction of Al3+ ions to Al metal.
Effect of increasing [Al3+]:
Le Chatelier's Principle:
According to Le Chatelier's principle, when a system at equilibrium is subjected to a stress, it will respond in such a way as to minimize the effect of that stress.
Increase in [Al3+]:
When the concentration of Al3+ ions is increased in the half-cell, it can be considered as an increase in the concentration of reactants. This will create a stress on the system and the equilibrium will shift in the direction that consumes the excess reactant.
Effect on Electrode Potential:
The electrode potential is a measure of the tendency of a half-cell to undergo reduction. It is directly related to the equilibrium constant of the half-cell reaction.
Increased Concentration of Reactants:
By increasing the concentration of Al3+ ions, the reactant concentration is increased. According to Le Chatelier's principle, the equilibrium will shift in the direction that consumes the excess reactant. In this case, the excess reactant is Al3+ ions.
Shift of Equilibrium:
The equilibrium will shift to the left, consuming the excess Al3+ ions. This means that the concentration of Al3+ ions will decrease, and the concentration of Al metal will increase.
Effect on Electrode Potential:
As the concentration of Al3+ ions decreases, the equilibrium constant of the half-cell reaction will also decrease. This leads to a decrease in the electrode potential of the half-cell.
Answer:
Therefore, on increasing the concentration of Al3+ ions, the electrode potential of the half-cell will decrease (Option B).
