SUMMARY

The Miller-Urey experiment, designed to simulate early Earth conditions, takes a considerable amount of time due to its unique reaction dynamics. Unlike typical chemical reactions that occur uniformly throughout a volume, the Miller-Urey experiment relies on a localized spark to stimulate reactants, which limits the reaction's overall rate. This localized stimulation means that only a specific area of the reaction mixture is actively undergoing transformation at any given time, contributing to the extended duration of the experiment.

PREREQUISITES
  • Understanding of chemical reaction kinetics
  • Familiarity with the principles of abiogenesis
  • Knowledge of the components used in the Miller-Urey experiment

I'm trying to find out why this experiment takes so long to run. I posted a similar question in the biology section but I think this question deals more with the chemistry aspect.

In most reactions, the activity is happening everywhere. Pick any volume of the reaction and you will find the reaction occurring at its particular rate. The Miller Urey experiment has this spark... it's the only place where reactants are being 'stimulated' to react. It isn't a particularly large volume relative to the whole.
