NEET Chemistry (general) MCQ Question
Which of the following statements about electrochemical cells and Gibbs energy are correct?
The standard Gibbs energy change can be calculated from the cell potential using the equation ΔrG° = -nFE°cell.
A higher cell potential indicates a lower equilibrium constant for the reaction.
The relationship ΔrG° = -RT ln K can be derived from the standard cell potential.
The equilibrium constant K can be influenced by the concentrations of reactants and products in an electrochemical cell.
Correct Answer
Detailed Explanation
The correct statement is A, as it directly relates to the calculation of standard Gibbs energy from cell potential. Statement B is incorrect because a higher cell potential corresponds to a higher equilibrium constant. Statement C is misleading as it implies the derivation is straightforward without specifying conditions. Statement D is not directly related to the definitions provided in the context.
