Rates And Energy
- How Fast?
- We can find the rate of a chemical reaction by mesureing the amount of reactonts
Used up over time or mesuring the amount of reactonts over time
- Collision Theory And Surface Area
- Particals must collide with a certain amount of
energy before they can react
- The Effect Of Themperiture
- Reaction happen more quickly as the
temperature increases
- The Effect Of Concentration Or Pressure
- Increasing the consentration of reactence in solotion
- The Effect Of Catalysts
- A catalyst speeds up the rate of a
chemical reaction
- Catalysts In Action
- Catalyst are used in industry to increase the rate
of reaction and reduce energy cost.
- Exothermic And Endothermic Reactions
- Energy mat be transferred to or from the
reacting substance in a reaction
- Energy And Reversible Reaction
- In reversable reactions the reaction is in one
direction is endo thermic and the other
direction is exothermic
- Using Energy Transfers From Reactions
- Exthertmic changes can be used in hand warmers and self heating
cans. Endothermic changes can be used in instant cold pack for
sports injuries
