question 19

Multiple Choice

A solution of chloroform, CHCl₃, and acetone, (CH₃) ₂CO, exhibits a negative deviation from Raoult's law. This result implies that

• A) chloroform-chloroform interactions are stronger than chloroform-acetone interactions.
• B) chloroform-chloroform interactions are weaker than chloroform-acetone interactions.
• C) acetone-acetone interactions are stronger than chloroform-acetone interactions.
• D) acetone-acetone interactions are weaker than chloroform-acetone interactions.
• E) Both B and D.
• F) Both A and C.

Definitions:

Relative Frequency Distribution

A table or chart that displays the relative frequencies of different categories or values in a dataset.

Class Boundaries

The values that sit between classes in a frequency distribution, used for continuous data to separate different classes.

Discrete Data

Data that can only take on specific values and cannot be made more precise by further measuring or subdividing.

Skewed Left

A distribution characterized by a longer tail on the left side, suggesting that the bulk of data is concentrated to the right of the mean.
