What you will be able to do
- 01List the factors that affect reaction rate
- 02Explain how each factor changes the rate
- 03Apply the factors to everyday and industrial situations
Chemists can speed up or slow down a reaction by controlling a small set of factors. Five stand out: the nature of the reactants themselves, the concentration of the reactants, the temperature, the surface area of any solids involved, and the presence of a catalyst. Learning what each does — and why — gives you control over almost any reaction.
