NEET Chemistry Van't Hoff Factor MCQ Question
In a laboratory experiment, you are given a diagram representing the dissociation of KCl in water at various concentrations. The diagram illustrates different levels of particle dissociation at concentrations of 0.1 m, 0.01 m, and 0.001 m. Which of the following best describes the trend in the van't Hoff factor as the concentration of KCl decreases?
The van't Hoff factor approaches 2.00 as concentration decreases.
The van't Hoff factor remains constant regardless of concentration.
The van't Hoff factor decreases as concentration decreases.
The van't Hoff factor approaches 1.00 as concentration decreases.
Correct Answer
Detailed Explanation
As per the NCERT context, the van't Hoff factor for KCl approaches 2.00 at lower concentrations due to complete dissociation.
