Question

I. Conductance of electrolyte solution increases with temperature.
II. Resistivity is reciprocal of molar conductivity of electrolyte.
III. Cell constant has unit $c{m}^{-1}$.

Which of the above statements are correct?

• A. All the statements are correct
• B. II and III are correct
• C. I and III are correct
• D. Only II is correct

Answer 1

The correct option is A All the statements are correct

we have,

1. conductance of electrolyte solution increase with temperature because of increase in their kinetic energy,

2. molar conductivity is directly proportional to specific resistance and reciprocal to resistivity,

3. cell constant = $\frac{l}{A}$ = $\frac{cm}{c{m}^2}$ = $c{m}^{-1}$
