question 123

Multiple Choice

Given the following data, estimate the boiling point of carbon disulfide, CS₂, assuming that $\Delta$ S ^$\circ$ and $\Delta$ H ^$\circ$ are temperature-independent. $\begin{array}{|l|c|c|}\hline & \Delta \mathrm{H}^{\circ}_f(\mathrm{kJ} / \mathrm{mol}) & \mathrm{S}^{\circ}(\mathrm{J} / \mathrm{K} \cdot \mathrm{~mol}) \\\hline \mathrm{CS}_{2}(g) & 115.3 & 237.8 \\\hline \mathrm{CS}_{2}(l) & 87.3 & 151.0 \\\hline\end{array}$

• A) 47.4^\(\circ\)C
• B) 49.4^\(\circ\)C
• C) 51.4^\(\circ\)C
• D) 53.4^\(\circ\)C
• E) None of the above

Definitions:

Independent Variables

Variables in an analysis that are manipulated or categorized to determine their effect on dependent variables.

Sample Size

The number of observations or elements included in a sample drawn from a population for analysis.

Estimated Multiple Regression

A statistical technique that estimates the relationship between a dependent variable and multiple independent variables.

Regression Plane

The regression plane is a three-dimensional graphical representation used in multiple regression analysis that shows the relationship between two independent variables and one dependent variable.
