Study Notes
Energy Diagram Concepts
- Reactants: The initial substances that undergo a chemical reaction to form products.
- Forward Activation Energy (Ea): The energy threshold needed to break atomic bonds during the forward reaction, facilitating the transformation from reactants to products.
Thermodynamics of Reactions
- Enthalpy (∆H): Represents the change in heat during a reaction calculated by the difference in potential energy between products and reactants.
Reaction Mechanism
- Activation Complex: The transitional state where all atomic bonds are broken, allowing atoms to rearrange and form new bonds.
- Activation Complex Energy: The peak energy level required to reach the activation complex, marking the highest energy state during the reaction.
Reverse Reaction Dynamics
- Reverse Activation Energy: The energy needed to break the bonds in the products to revert back to the original reactants in the reverse reaction.
Potential Energy Context
- PE Products / PE Reactants: Compares the potential energy of products in a forward reaction against the potential energy of reactants.
- PE Reactants / PE Products: Contrasts the potential energy of reactants in a forward reaction with the potential energy of products in the reverse reaction.
