Energy Profile Modeler

Adjust the energy profile, study the labels, or quiz yourself on reaction energetics.

40 kJ mol⁻¹
100 kJ mol⁻¹
80 kJ mol⁻¹

Activated complex energy = forward reactants PE + forward activation energy.

In quiz mode, students should check their answers first, then export the PNG for submission.
