WebScienceChemistryConcept question: If given a reaction with the ΔH, how do we determine how much activation energy is needed for the reaction to begin? Does it differ if it was exothermic or endothermic reaction? Do exothermic reactions require an initial input of twice the bond energy of the reactants? WebActivation Energy has to be supplied to the mixture – and then there will be not just a reaction but (if there are sufficient quantities of the two reactants) there will be an explosion. Activation Energy is the minimum amount of energy that must be supplied to the reactants in a reaction in order for the reaction to commence.
