Questions & Step-by-Step Solutions
If the concentration of reactants in a redox reaction is doubled, how does it affect the cell potential according to the Nernst equation?
Step 1: Understand that a redox reaction involves reactants and products, and their concentrations can affect the reaction's behavior.
Step 2: Familiarize yourself with the Nernst equation, which relates the cell potential (E) to the concentrations of reactants and products.
Step 3: Recognize that in the Nernst equation, Q represents the reaction quotient, which is calculated using the concentrations of the products and reactants.
Step 4: When the concentration of reactants is doubled, the value of Q increases because the reactants are in the denominator of the equation for Q.
Step 5: According to the Nernst equation, if Q increases, the cell potential (E) decreases.
Step 6: Conclude that doubling the concentration of reactants leads to a decrease in cell potential.
