Study Notes
Chemical Reaction Theories
- The collision theory explains how chemical reactions occur focusing on particle collisions and energy transfer.
- Factors affecting reaction rates include concentration, temperature, surface area, and the presence of catalysts.
Atomic Interaction
- Chemical bonding involves the interaction between atoms, particularly the valence electrons of one atom and the nucleus of another.
Chemical Reaction Process
- During a chemical reaction, bonds between atoms break and new bonds form, resulting in the formation of different substances (products).
Activation Energy
- Activation energy is the minimum energy required to initiate a chemical reaction and overcome the energy barrier for bond breaking.
Low Activation Energy Effects
- If the activation energy is low, reactions can occur at lower temperatures, increasing reaction rates and dynamics.
Energy Sources for Reactions
- Reactants require energy from various sources such as heat, light, or electricity to initiate chemical reactions and facilitate bond breaking.
Conditions for No Reaction
- No reaction will occur under conditions where reactants are at very low energy states or lack sufficient activation energy to overcome barriers.
Collision Requirements
- Even with particle collisions, if the reactants do not have the correct orientation or enough energy, a reaction may not occur.
Energy Levels of Reactants and Products
- A reaction cannot proceed spontaneously if the reactants have less stored energy compared to the products; sufficient activation energy is needed to convert them.
