Rates And Energy

How Fast?
1. 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
1. Particals must collide with a certain amount of energy before they can react
The Effect Of Themperiture
1. Reaction happen more quickly as the temperature increases
The Effect Of Concentration Or Pressure
1. Increasing the consentration of reactence in solotion
The Effect Of Catalysts
1. A catalyst speeds up the rate of a chemical reaction
Catalysts In Action
1. Catalyst are used in industry to increase the rate of reaction and reduce energy cost.
Exothermic And Endothermic Reactions
1. Energy mat be transferred to or from the reacting substance in a reaction
Energy And Reversible Reaction
1. In reversable reactions the reaction is in one direction is endo thermic and the other direction is exothermic
Using Energy Transfers From Reactions
1. Exthertmic changes can be used in hand warmers and self heating cans. Endothermic changes can be used in instant cold pack for sports injuries
