∧m is linearly dependent to √c for an electrolyte, then molar conductance for the same electrolyte at infinite dilution shows

Question

\(\wedge_m\) is linearly dependent to \(\sqrt c\) for an electrolyte, then molar conductance for the same electrolyte at infinite dilution shows 

(1) Small increase 

(2) Small decrease 

(3) Sharp increase 

(4) Sharp decrease

Answer 1

Correct option is (1) Small increase 

\(^\wedge m\) decreases linearly with \(\sqrt c\) for strong electrolytes having small –ve slope. It can be extrapolated to \(\wedge^\infty_ m\) as c → 0.  

The molar conductance of the same electrolyte at infinite dilution or as c \(\rightarrow 0\) shows small increase.
