- Chemical Reactions
- Reactants must collide with sufficient energy to break old bonds
- an exothermic reaction gives out energy
- an endothermic reaction takes in energy

- Reactants must collide with sufficient energy to break old bonds
- an exothermic reaction gives out energy
- an endothermic reaction takes in energy
- an endothermic reaction takes in energy
- breaking bonds is endothermic
- Making bonds is exothermic
- reaction rate is the rate reactants are used up
- Changes in concentration of the reactants temperature and surface area changes the reaction rate
- Catalysts are used to increase reaction rates
- catalytic converters in cars convert carbon monoxide and unburnt hydrocarbons to CO2 and Water
