WebJun 9, 2024 · The activation energy for a reaction is the minimum energy that colliding particles must have in order to undergo a reaction. Some reactions occur readily at room temperature because most of the reacting particles already have the requisite activation energy at that temperature. WebChemical thermodynamics is the portion of thermodynamics that pertains to chemical reactions. The Laws of Thermodynamics First law: Energy is conserved; it can be neither created nor destroyed. Second law: In an isolated system, natural processes are spontaneous when they lead to an increase in disorder, or entropy. WebSep 16, 2024 · In order for a reaction to be effective, particles must collide with enough energy, and have the correct orientation.
