Free Energy Lab

Instructions

Connect particle dispersal, entropy and Gibbs free energy. Predict before checking your answer.

  1. Choose a mode and a reaction or process.
  2. Predict a sign or enter a calculation, then press Check.
  3. Convert entropy from J to kJ before using ΔG = ΔH − TΔS.
  4. Compare diagrams with the Data table. Copy or download your data.
