Chapter 17 Rate of Reactions

• Collision Theory

  1. Effective collision : when reactant particles collide w/ energy greater than or equal to activation energy
  2. Causes existing bonds to be broken and new bonds to be formed
  3. When frequency of effective collision increases, rate of reaction increases
  4. Can be increased by : increasing frequency of collisions or increasing energy of reactant particles
• Investigating How Different Factors Affect the Rate of Reaction

  
  

  • Must show that you know which factors are constant
  • Refer to Chem Revision Guide pg 195
