16.2 Activation energy

Arrhenius Equation

Arrhenius Equation

  • Uses temperature dependence of the rate constant to determine activation energy
  • The “Frequency factor”, A, takes into account the frequency of collisions with proper orientations
  • The graph of lnk against 1/T is a linear plot with gradient -Ea/R and intercept lnA
  • Only way to learn this is to do practice questions
