Which option correctly explains how the concentration of ions in electrolyte solutions affects the standard cell potential?
More concentrated solutions decrease the rate at which the half-reaction occurs and will decrease the E0.
More concentrated solutions will increase the rate at which the half-reactions occur initially and then will decrease it. Thus they will first increase the E0, and then decrease it.
The concentration of solutions may increase or decrease E0, depending on the nature of the electrode.
More concentrated solutions increase the rate at which the half-reaction occurs and will increase the E0.
C?
I would not have chosen C. \What is your rationale?
B? I don't really have a rationale tbh
The correct option that explains how the concentration of ions in electrolyte solutions affects the standard cell potential is:
More concentrated solutions increase the rate at which the half-reaction occurs and will increase the E0.
Explanation:
The concentration of ions in the electrolyte solution has an effect on the standard cell potential (E0) of a electrochemical cell. The E0 measures the driving force or the tendency of a redox reaction to occur.
When the electrolyte solution is more concentrated, there are more ions available to participate in the redox reaction. This increases the collision frequency between the reactants, leading to an increase in the rate at which the half-reaction occurs. As a result, the standard cell potential (E0) increases.
Therefore, it is important to note that an increase in the concentration of ions in electrolyte solutions generally leads to an increase in the standard cell potential.
