Chemical reaction rate and chemical reaction progress are very similar concepts and knowledge

and closely related to each other at the same time. They describe the extent of change at a macro level or superficial level

but both have completely different nature

one is dynamic quantity

the other is thermodynamic quantity; one is microscopic property and the other is macroscopic property. By analyzing the free radical polymerization of methyl methacrylate (MMA)

the connotation and significance of reaction rate and reaction progress were discussed

and the dialectically essential relationship between them was revealed too. Therefore

the work will make students further enhance theoretical knowledge on how to improve polymer yield

molecular weight

and promote the improvement of learning ability

moreover

it will be of great significance to improve students' practical ability and innovative ability in future work.
