In a galvanic cell, after running the cell for sometime, the concentration of the electrolyte is automatically raised to 3 m HCl. Molar conductivity of the 3 m HCl is about 240 Scm2mol-1and limiting molar conductivity ofHClis about 420 Scm2mol-1. IfKbof water is 0.52 K kgmol-1, calculate the boiling point of the electrolyte at the end of the experiment.

Options:

Answer:
A
Solution:

α=Molar conductivityLimiting molar conductivity=240420=1221

α=i-1n-1=i-12-1=1221

i=1221+1=3321

ΔTb=iKbm=3321×0.52×3=2.45K

Tb=Tbo+ΔTb=373.15+2.45=375.6K
