Topics in Chemical Kinetics

1

Rate of Chemical Reaction

  • Rate of reaction is the change in concentration of reactants or products per unit time
  • Rate = -Δ[R]/Δt for reactants (negative sign because concentration decreases)
  • Rate = +Δ[P]/Δt for products (positive sign because concentration increases)
2

Factors Affecting Rate of Reaction

  • Concentration of reactants: Higher concentration generally increases rate
  • Temperature: Rate approximately doubles for every 10°C rise
  • Catalyst: Provides alternate pathway with lower activation energy
3

Rate Law and Rate Constant

  • Rate law: Rate = k[A]ˣ[B]ʸ where x,y are experimental orders
  • Rate law must be determined experimentally, not from balanced equation
  • Rate constant k is specific for each reaction at given temperature
4

Order and Molecularity

  • Order: Sum of exponents in rate law (can be 0, fraction, or integer)
  • Molecularity: Number of molecules participating in elementary reaction
  • Order is experimental, molecularity is theoretical
