This question matches electrochemical properties with their characteristics. Let's analyze each term:
(A) Molar conductance (λm) is conductance per mole. It is an intensive property (P) and increases with dilution (R) for weak electrolytes.
(B) represents the standard electrode potential (E°). It is an intensive property (P) and is temperature dependent (S).
(C) Conductivity (K) is an intensive property (P) and generally increases with concentration (T) for strong electrolytes.
(D) ΔG°cell is the standard free energy change. It is an extensive property (Q) as it depends on the number of moles (n) and is temperature dependent (S).
Final Answer: (A) → P,R; (B) → P,S; (C) → P,T; (D) → Q,S
