What is the Nernst equation used for calculating the cell potential at non-standard conditions? (2023)

Step 1: Understand that the Nernst equation helps us find the cell potential (E) when conditions are not standard.
Step 2: Identify the components of the Nernst equation: E = E° - (RT/nF)lnQ.
Step 3: Recognize that E° is the standard cell potential, which is the potential under standard conditions.
Step 4: Know that R is the gas constant, which is approximately 8.314 J/(mol·K).
Step 5: Remember that T is the temperature in Kelvin (K).
Step 6: Understand that n is the number of moles of electrons transferred in the reaction.
Step 7: Identify F as Faraday's constant, which is about 96485 C/mol.
Step 8: Learn that Q is the reaction quotient, which represents the ratio of products to reactants at any point in the reaction.
Step 9: Plug in the values for E°, R, T, n, F, and Q into the Nernst equation to calculate E.
