Enduring Understanding (s): All reactions require activation energy, which can be controlled by catalysts. _________________________________________________
Essential Question (s): What is the SI unit for energy? What is the first law of thermodynamics? On a potential energy diagram, what does the activation energy tell you? _______________________________________________________
