Reaction Time for Trimolecular Reactions in Compartment-based   Reaction-Diffusion Models
  Trimolecular reaction models are investigated in the compartment-based (lattice-based) framework for stochastic reaction-diffusion modelling. The formulae for the first collision time and the mean reaction time are derived for the case where three molecules are present in the solution.
