{"knowledge_schema": {"broad_category": "Chemistry \u2192 Electrochemistry \u2192 Nernst Equation", "refinement": "The Nernst equation relates the cell potential of an electrochemical reaction to the concentrations of the reactants and products involved in the reaction.", "specific_scope": "The focus is on understanding how the Nernst equation modifies the standard cell potential based on the actual concentrations of the species in the reaction.", "goal": "Identify the correct statement regarding the Nernst equation and its application in electrochemistry."}, "summary": "The Nernst equation is a fundamental concept in electrochemistry that describes how the cell potential varies with the concentrations of reactants and products. It specifically accounts for the effect of concentration on cell potential, allowing for the calculation of the potential under non-standard conditions. The goal is to recognize that the Nernst equation is not limited to standard conditions, acidic solutions, or solely for calculating equilibrium constants, but rather it adjusts the cell potential based on the actual concentrations present."}
