Thermodynamics govern reactions occur

Click For Summary

Discussion Overview

The discussion focuses on the concepts from thermodynamics that govern whether chemical reactions occur. It touches on various factors such as activation energy, entropy, and free energy, exploring their roles in reaction dynamics and equilibrium.

Discussion Character

  • Homework-related
  • Conceptual clarification

Main Points Raised

  • One participant mentions activation energy as a necessary factor for reactions, suggesting that energy sources like pressure or light are needed to initiate reactions.
  • The same participant raises a question about the role of entropy in determining reaction occurrence, expressing uncertainty about its significance.
  • Another participant inquires about the relationship between free energy and equilibrium constants, indicating a connection to thermodynamic principles.
  • A follow-up question seeks clarification on how the change in free energy (ΔG) relates to the equilibrium constant (K) and what the equilibrium constant indicates about the reaction.

Areas of Agreement / Disagreement

The discussion does not present a consensus, as participants express varying levels of understanding and inquiry regarding the concepts of activation energy, entropy, and free energy in relation to reactions.

Contextual Notes

Participants have not fully explored the definitions and implications of entropy and free energy, leaving some assumptions and relationships unresolved.

Homework Statement


What concepts from Thermodynamics govern whether reactions occur or not?


Homework Equations





The Attempt at a Solution



Activation energy-need some source of energy to start it-like pressure or light.
Entropy-but why?

Anything else, I'm sure there is more, but I don't understand it very well.

Have you studied about how free energy relates the equilibrium constants of reactions?
 
like the K constant?
 
Yes. How is the change in free energy during a reaction (ΔG) related to the equilibrium constant (K)? What does the equilibrium constant tell you about the reaction?
