Select:
- heat the substances
- increase the concentration of one of the substances
- crush up one of the substances
Why: Heating raises molecular energy and collision frequency, increasing the chance of overcoming activation energy. Increasing concentration raises collision frequency. Crushing a solid increases its surface area and contact between reactants. Cooling or decreasing concentration would usually make a reaction less likely.
