Collision Theory - Rate Constant

Rate Constant

The rate constant for a bimolecular gas phase reaction, as predicted by collision theory is:

.

where:

  • Z is the .
  • is the steric factor.
  • Ea is the activation energy of the reaction.
  • T is the temperature.
  • R is gas constant.

The collision frequency is:

where:

  • NA is the Avogadro constant
  • σAB is the reaction cross section
  • kB is Boltzmann's constant
  • μAB is the reduced mass of the reactants.

Famous quotes containing the words rate and/or constant:

    You are more than entitled not to know what the word ‘performative’ means. It is a new word and an ugly word, and perhaps it does not mean anything very much. But at any rate there is one thing in its favor, it is not a profound word.
    —J.L. (John Langshaw)

    There’s nothing constant in the world,
    All ebb and flow, and every shape that’s born
    Bears in its womb the seeds of change.
    Ovid (Publius Ovidius Naso)
