Why is the active mass of solids taken as unity?

Click For Summary
SUMMARY

The active mass of solids is conventionally taken as unity in chemical reactions due to the constant density of solids and liquids. This simplification facilitates calculations, as using 1 as a value for active mass streamlines the mathematical representation of reactions. The rationale behind this convention is rooted in the practicality it offers in stoichiometric calculations.

PREREQUISITES
  • Understanding of chemical reaction dynamics
  • Familiarity with the concept of active mass in chemistry
  • Basic knowledge of stoichiometry
  • Awareness of the properties of solids and liquids in reactions
NEXT STEPS
  • Research the concept of active mass in chemical kinetics

Homework Statement


I understood the fact that since the density of solids and liquids remain constant in a reaction therefore the active mass must be a constant.But why is it that we take it as unity. Is is some kind of coonverntion,or is there a reason behind it?
