Select:
- crush up one of the substances
- heat the substances
- increase the concentration of one of the substances

Reason: Crushing increases surface area (more contact), heating increases collision energy/frequency (helps overcome activation energy), and increasing concentration raises collision frequency. Cooling or decreasing concentration would slow the reaction.
