Branch of chemistry that deals with the rates of chemical reactions TOPIC 8 Review Book

 In order for a chemical reaction to occur, particles must have EFFECTIVE COLLISIONS  Effective collisions must occur for old bonds to be broken and new bonds to be formed  What is an effective collision?  An effective collision must have enough energy and the proper orientation watch?v=mBTSwJnZ6Sk

 Nature Covalently bonded react more slowly than ionic because there are more bonds to break  Concentration If concentration of one or more reactants is increased, reaction rate increases  Surface area Greater surface area = faster reaction rate  Pressure Increase in pressure = increase in reaction rate of GASES  Catalyst Increase reaction rate by providing alternate pathway  Temperature Increase temperature = increased reaction
