Activation energy ( Ea ) and the Enthalpy of reaction (ΔH)

Activation energy & chemical Reaction – chemistry Study notes

Activation energy is the minimum energy required to start a chemical reaction. The colliding particles must possess at least this amount of energy for a reaction to take place. Most of the reactions are exothermic but only a few are totally spontaneous and begin without help at normal temperatures (e.g. sodium or potassium reacting with […]
