Science
Reaction rates.
Definition
Reaction rate measures how quickly reactants are consumed or products are formed in a chemical reaction. Rates are affected by temperature, concentration, surface area, catalysts, and the nature of the reactants.
Examples
Real-world.
- 1 Iron rusting slowly at room temperature but faster in saltwater
- 2 Food spoiling faster when left out of the refrigerator
- 3 Crushing a tablet so it dissolves faster than a whole tablet
Key Fact
Rate = −Δ[reactant]/Δt = +Δ[product]/Δt
