Concept explainers

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Question

### Educational Resource on Trouton's Rule

**Understanding Trouton's Rule**

Trouton's rule states that the molar enthalpy of vaporization (ΔH_vap) of a liquid that lacks strong molecular interactions (such as hydrogen bonding or ion-ion attractions) can be estimated using the relationship:

\[ \Delta H_{\text{vap}} = \left( 85 \: \text{J} \cdot \text{K}^{-1} \cdot \text{mol}^{-1} \right) T_b \]

where:
- \( \Delta H_{\text{vap}} \) is the molar enthalpy of vaporization.
- \( T_b \) is the normal boiling point of the liquid in kelvins (K).

### Data Table

The table below lists the chemical formulas, molar enthalpies of vaporization (ΔH_vap), boiling points (in K), and molar enthalpies of fusion (ΔH_fus) for different compounds:

| Compound | Chemical formula | \( \Delta H_{\text{vap}} \) (kJ·mol\(^{-1}\)) | Boiling point (K) | \( \Delta H_{\text{fus}} \) (kJ·mol\(^{-1}\)) |
|----------------------|-------------------|----------------------------------|-------------------|---------------------------------|
| chloromethane | CH\(_3\)Cl | 21.40 | 249.06 | 6.43 |
| water | H\(_2\)O | 40.65 | 373.15 | 6.01 |
| hydrogen sulfide | H\(_2\)S | 18.67 | 213.60 | 18.67 |

### Applying Trouton's Rule

To estimate the value of \( \Delta H_{\text{vap}} \) for chloromethane using Trouton's rule, substitute the normal boiling point (\( T_b \)) of chloromethane into the equation:

\[ \Delta H_{\text{vap}} = ( 85 \: \text{J} \cdot \text{K}^{-1} \cdot \text{mol}^{-1} ) \times T_b \]

Given:
- \( T_b \) for chloromethane = 249.06 K

Ethanol, with ΔHvap = 40.5 kJ mol-1, has a higher ΔHvap than methanol, which is 35.2 kJ mol-1, due to its larger size and greater intermolecular forces. Because the ΔHvap for ethanol is larger, we would expect that for the two liquids to reach the same vapor pressure, the temperature for ethanol would have to be higher. If the vapor pressure is 0.0992 atm at 27.3 °C, what would the temperature be when the vapor pressure is 4.52 atm?
Why does the vapor pressure of a liquid decreases as the strength of its intermolecular forces increases?
