Match the items in Column I with their description in Column II S.No. Column I S.No. Column II A Kappa K P Intensive property. B E_ cell ^0 Q Extensive property. C Molar conductivity R Decreases with decrease in concentration of both strong and weak electrolytes. D G_ cell S Increases with dilution.
Options
- AA = Q B = S C = P D = R
- BA = R B = Q C = S D = P
- CA = R B = P C = S D = Q
- DA = S B = R C = Q D = P
Correct answer
C. A = R B = P C = S D = Q
Step-by-step solution
Kappa (K) is the specific conductivity, which is defined as the conductance of a unit volume of solution. It decreases with a decrease in concentration (dilution) because the number of ions per unit volume decreases. Standard cell potential ( E_ cell ^0 ) is an intensive property because it does not depend on the amount of substance in the system. Molar conductivity ( _m ) is defined as the conductivity of a solution containing one mole of electrolyte. It increases with dilution because the volume of the solution c
