NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Imagine a graph depicting the variation of molar conductivity (Λm) with the square root of concentration (c½) for different electrolytes. Which of the following correctly describes the intercept and slope of the line for a strong electrolyte like NaCl?
A
Intercept is Λ°m and slope is -A
B
Intercept is -A and slope is Λ°m
C
Intercept is 0 and slope is A
D
Intercept is Λ°m and slope is A
Correct Answer
Option A
Detailed Explanation
For strong electrolytes, the plot of Λm against c½ is a straight line with an intercept equal to Λ°m and a slope equal to -A as per the equation Λm = Λ°m - A c½.
