The resistances of following solutions of KCl were measured using conductivity cells of different cell constants, at same temperature. (Consider that at concentration less than 0.1 M, the specific conductivity of solution is directly proportional to the concentration of solution.)
Concentration of Solution | Cell Constant | |
1. | 0.1 M | 1 cm–1 |
2. | 0.01 M | 10 cm–1 |
3. | 0.005 M | 5 cm–1 |
4. | 0.0025 M | 25 cm–1 |
Which of the following comparisons between their conductances (G) is/are correct ?

(a,b) 
Hence 
= a x 0.1
= a x 0.01
= a x 0.005
= a x 0.0025
G = 
So, 
; 
= 0.1 a = 0.001 a
; 
= 0.001a = 0.0001 a
Hence G 1 > G 2 = G 2 > G 4
