Equilibria

Equilibrium and Gibbs free energy

No items found.

Explore how the equilibrium constant is related to Gibbs free energy, enthalpy and entropy. Practise rearranging equations involving these properties and apply your knowledge to problems involving the binding affinity of different ligands to heavy metals.

Learning outcomes

  • Recall fundamental principles in equilibrium and apply them to solve problems involving reaction quotients.
  • Calculate Gibbs free energy changes given enthalpy and entropy changes.
  • Make assessments on the spontaneity of the reaction based on the sign of the Gibbs free energy change.
  • Solve problems involving equilibrium constants and Gibbs free energy.
  • Rearrange equations to derive the van 't Hoff equation and use this to solve problems.

"I find Smart Worksheets a lot less stressful than full written lab reports and much easier to cope with in terms of my ADHD and anxiety. I feel that they allow people with learning difficulties to be assessed in a way that is more beneficial to our needs, and help us get the marks we may have lost out on in assignments with large chunks of writing, or take a lot longer to do."
