Correct Answer: Nernst equation is used to find cell potential.
Step 1: Understand that the Nernst equation relates to electrochemistry, which is the study of chemical reactions that produce electricity.
Step 2: Know that a cell potential is the voltage produced by an electrochemical cell.
Step 3: Recognize that standard conditions refer to specific concentrations and temperatures where the cell potential is measured.
Step 4: Realize that the Nernst equation helps calculate the cell potential when the conditions are not standard, meaning concentrations or temperatures are different.
Step 5: Use the Nernst equation to find out how much voltage a cell will produce in real-life situations, which may vary from the standard values.
