.. autoclass:: rmgpy.kinetics.ThirdBody
Third-body kinetics simply introduce an inert third body to the rate expression:
.. math:: k(T,P) = k_0(T) [\mathrm{M}]
Above, :math:`[\mathrm{M}] \approx P/RT` is the concentration of the bath gas.
This formulation is equivalent to stating that the kinetics are always in the
low-pressure limit.
