AIIMS 2019 Chemistry Gibbs Free Energy MCQ Question

Option A is correct because the derivation of the equation ΔG = −RTln(K/Q) accurately reflects the relationship between the Gibbs free energy change (ΔG), the standard Gibbs free energy change (ΔG°), and the reaction quotient (Q) at non-equilibrium conditions. When ΔG = 0 and Q = K, it leads to the conclusion that ΔG° = −RTlnK, which is then substituted back into the original equation, demonstrating how ΔG varies with the ratio of the equilibrium constant (K) to the reaction quotient (Q). Other options are not applicable as they do not provide relevant information or alternative answers to the derivation presented.
