Answers:
- NOT ways to speed up the reaction: decreasing the temperature of a reactant, and decreasing the surface area of a reactant.
- Ways that do speed up the reaction: increasing the concentration of a reactant and increasing the temperature.
Reason: Lowering temperature and reducing surface area both lower collision frequency/energy and slow the rate; increasing concentration or temperature increases collision frequency and/or energy and speeds the reaction.
