IB DP Chemistry R1.4 L1 | Entropy as Dispersal of Matter and Energy | Lesson Walkthrough
Build a particle-level interpretation of entropy through the dispersal of matter and energy. Students compare possible arrangements and make qualitative predictions about entropy changes.
IB DP Chemistry R1.4 L2 | Calculating Standard Entropy Changes | Lesson Walkthrough
Calculate standard entropy changes from tabulated data. Students predict a sign and approximate scale first, then check stoichiometric coefficients, units and the physical interpretation of the result.
IB DP Chemistry R1.4 L3 | Gibbs Energy | Lesson Walkthrough
Combine enthalpy, entropy and temperature through the Gibbs energy equation. Students calculate energy changes with consistent units and explain how the terms determine thermodynamic favourability.
IB DP Chemistry R1.4 L4 | Spontaneity and the Temperature at Which Direction Changes | Lesson Walkthrough
Use Gibbs energy to investigate how thermodynamic favourability changes with temperature. Students interpret graphs, compare sign combinations and calculate threshold temperatures.
IB DP Chemistry R1.4 L5 | Gibbs Energy, Reaction Quotient and Equilibrium | Lesson Walkthrough
Distinguish standard Gibbs energy from Gibbs energy under current conditions. Students connect reaction quotient, equilibrium constant and energy changes to predict direction and interpret equilibrium.
