In the field of electrochemistry, which statement correctly describes the concept and implications of the Nernst equation in relation to electrochemical cells? A) The Nernst equation is only applicable to galvanic cells and cannot be used to describe the behavior of electrolytic cells under any circumstances. B) According to the Nernst equation, the cell potential is directly proportional to the temperature of the system, regardless of the concentration of the reactants and products. C) The Nernst equation allows the calculation of the cell potential under non-standard conditions, taking into account the concentrations of the reactants and products, temperature, and standard electrode potentials. D) In the Nernst equation, the influence of pressure on the cell potential is considered as the primary factor, while the effects of concentration and temperature are generally negligible.
