3D Atomic Orbital Viewer
Spin real s, p and d orbitals in 3-D, fill the energy levels electron by electron, then watch the d orbitals split in an octahedral field to explain complex-ion colour — with a practice mode that marks your configurations.
- Orbital shapes
- Electronic configuration
- d-orbital splitting
- Complex colour
VSEPR Shape Viewer
Every molecular shape in 3-D — count electron domains and lone pairs to fix the shape, spin real molecules, predict from a formula and compare bond angles.
- Electron domains
- Lone pairs
- Molecular shape
- Bond angles
Ideal & Real Gas Simulator
Slide p, V, n and T and watch pV = nRT stay balanced in a live particle box — then switch to a real gas and see where ideal behaviour breaks down, and why.
- Kinetic theory
- Gas laws
- pV = nRT
- Dalton's law
- Real gases
Gibbs Free Energy & Spontaneity
Slide ΔH, ΔS and T and watch ΔG = ΔH − TΔS trace a straight line — find the temperature where a reaction turns feasible, and see why spontaneous doesn't mean fast.
- Entropy
- Sign of ΔS
- ΔG = ΔH − TΔS
- Feasibility
Electrolysis Predictor
Set up any electrolytic cell, predict the product at each electrode, then run it to check against an animated cell — and work the Faraday sums, F = 96 500 C mol⁻¹, both ways.
- Discharge rules
- Half-equations
- Q = It, n = Q/F
- Copper purification
- Anodising
Boltzmann Distribution
Slide the temperature and activation energy and watch the shaded tail beyond Eₐ grow — see why heating and catalysts speed reactions up, with a live particle box and a theory primer.
- Activation energy
- Maxwell–Boltzmann
- Effect of temperature
- Catalysis
