Chapter 14: Chemical Kinetics

Rates of reaction and the particulate nature of matter

• Kinetics:
  • Rates of reaction (speed)
  • The sequential steps of a reaction
• Affect the rates?
  • Concentration of the reactants
    • The more stuff that is present, the more collisions will occur and the rate of reaction will increase
  • Temperature of reaction
    • As the temperature increases, the rates also increase
  • Structure and orientation of particles
    • B-A + C ---> A-C + B
    • A-B + C -/->
      

Rates in a chemical reaction

• Rate = $\frac{\text{Concentration Change}}{\text{Time Change}}$
• 2 N2O5 -> 4NO2 + O2
• Rate of formation for NO2: $\frac{\Delta [NO_2]}{\Delta t}$
