Non-Equilibrium Systems

IQ1: What happens when chemical reactions do not go through to completion?

Students:

● analyse examples of non-equilibrium systems in terms of the effect of entropy and enthalpy, for example:

– combustion reactions

– photosynthesis

5. Non-Equilibrium Systems (Gibb)

This presentation introduces non-equilibrium systems (static equilibria) and relates this to photosynthesis and combustion.

This worksheet contains a range of problems on non-equilibrium systems.

5.5 Non-Eq Systems.docx

In the second lesson of Module 5 IQ1, we looked at "static equilibria" (non-equilibrium systems).

That lesson focused on terminology and conditions, this lesson focuses on using Gibbs Free Energy calculations to determine spontaneity.
