2) Polystyrene can be produced using numerous reaction pathways. One pathway involves to simply
heat styrene to temperatures just below its boiling point, leading to auto-polymerisation. One litre
of styrene contains 8.63 mol at the experiment's temperature. The below table contains the
measured styrene concentration at various time points.
