The London dispersion force between two neon atoms compared to the London dispersion force between two argon atoms where both systems are the most stable is: 1. the same 2. stronger 3. weaker Because: 1. They are both noble gases. 2. Neon has a smaller electron cloud, therefore there will be a smaller separation of charge resulting in a weaker force. 3. Neon has a smaller electron cloud, therefore there will be a larger separation of charge resulting in a stronger force. O 3,1 O 2,3 O 1,1 O 1,2 O 2,1

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
Question
Transcribed Image Text:### Understanding London Dispersion Forces between Noble Gases
The London dispersion force between two neon atoms compared to the London dispersion force between two argon atoms where both systems are the most stable is:
1. the same
2. stronger
3. weaker
#### Because:
1. They are both noble gases.
2. Neon has a smaller electron cloud, therefore there will be a smaller separation of charge resulting in a weaker force.
3. Neon has a smaller electron cloud, therefore there will be a larger separation of charge resulting in a stronger force.
### Options:
- ⚪ 3, 1
- ⚪ 2, 3
- ⚪ 1, 1
- ⚪ 1, 2
- ⚪ 2, 1
- ⚪ 3, 2
- ⚪ 2, 2
- ⚪ 3, 3
- ⚪ 1, 3
### Analysis:
This question tests the understanding of London dispersion forces (also known as induced dipole-induced dipole interactions) between noble gas atoms. The options provided list combinations of statements about the strength of these forces and their reasons.
### Key Points to Consider:
- **Noble Gases**: Both Neon (Ne) and Argon (Ar) are noble gases.
- **Electron Cloud Size**: Neon has a smaller electron cloud compared to Argon.
- **Charge Separation**: The size of the electron cloud affects the separation of charge, which in turn, affects the strength of the London dispersion force.
Students should use their understanding of how the size of atoms and the resulting induced dipole moments influence the intermolecular forces to select the correct answer combination.
