# SC4: Engineering Chemical Reaction Systems

Obtain, evaluate, and communicate information about how to refine the design of a chemical system by applying engineering principles to manipulate the factors that affect a chemical reaction.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SC4.a**: Plan and carry out an investigation to provide evidence of the effects of changing concentration, temperature, and pressure on chemical reactions.
- **SC4.b**: Construct an argument using collision theory and transition state theory to explain the role of activation energy in chemical reactions.
- **SC4.c**: Construct an explanation of the effects of a catalyst on chemical reactions and apply it to everyday examples.
- **SC4.d**: Refine the design of a chemical system by altering the conditions that would change forward and reverse reaction rates and the amount of products at equilibrium.
