SUMMARY

The discussion centers on approximating the specific heat capacity (Cp) of solid Benzoyl peroxide (BPO) using its gas phase Cp value of 454.39 J/molK. The Dulong and Petit law is mentioned as a potential method for this approximation. Participants express the need for literature values to validate their findings, indicating a gap in readily available data for solid BPO. The conversation highlights the importance of reliable sources for thermodynamic properties in chemical research.

PREREQUISITES
  • Understanding of specific heat capacity and its significance in thermodynamics
  • Familiarity with the Dulong and Petit law for estimating heat capacities
  • Knowledge of Benzoyl peroxide's chemical properties
  • Experience with literature research in chemical databases
NEXT STEPS
  • Research the application of the Dulong and Petit law in estimating solid heat capacities
  • Explore literature databases for published Cp values of solid Benzoyl peroxide
  • Learn about thermodynamic property estimation techniques in organic compounds
  • Investigate methods for validating experimental thermodynamic data
USEFUL FOR

Chemists, chemical engineers, and researchers involved in thermodynamics or materials science, particularly those studying the thermal properties of organic compounds.

TL;DR
I have the Cp of Benzoyl peroxide (BPO) in gas form (454.39 J/molK). What approximation could I make to find the Cp of solid BPO?
I have the Cp of Benzoyl peroxide (BPO) in gas form (454.39 J/molK). What approximation could I make to find the Cp of solid BPO as I cannot find this info online? thanks

Thanks! do you have any idea on how I would check the accuracy of my obtained value? I am not sure where to find a literature value
