The Nernst equation is an equation used to calculate the potential difference (E) between two half-cells in an electrochemical cell. It relates the potential difference to the standard potential (Eo) of the cell, the gas constant (R), the temperature (T), the Faraday constant (F), and the concentration (C) of the species involved in the redox reaction.
The Nernst equation is given by the following statement:
E = Eo - (2.303 RT/F) log C
Explanation:
- The Nernst equation describes the relationship between the potential difference (E) and the concentration (C) of the species involved in the redox reaction.
- The equation includes the standard potential (Eo) of the cell, which is the potential difference when the concentrations of the species are 1 M and the pressure of the gases involved is 1 atm.
- The gas constant (R) is a constant that relates the temperature (T) to the energy of a system.
- The Faraday constant (F) is a constant that relates the charge of an electron to the number of moles of electrons in a mole of substance.
- The logarithm (log) in the equation is used to calculate the ratio of the concentrations of the species involved in the redox reaction.
In option 'A', the correct form of the Nernst equation is given:
E = Eo - (2.303 RT/F) log C
- The equation includes the standard potential (Eo), which is subtracted from the term (2.303 RT/F) log C.
- The logarithm (log) is used to calculate the ratio of the concentration (C) of the species involved in the redox reaction.
- This equation allows us to calculate the potential difference (E) between two half-cells based on the concentration of the species involved in the redox reaction.
Therefore, option 'A' is the correct answer as it correctly represents the Nernst equation.
