FSC-1|11CLASS ChemistryTopic6.2 Energy Profile Diagram Showing Activation Energy and Enthalpy Change

This diagram shows the energy profile of a chemical reaction. The vertical axis represents energy, while the horizontal axis represents the progress of reaction. The energy level of the reactants is shown at the start of the reaction. As the reaction begins, the energy increases and reaches a maximum point called the activated complex. The energy required to reach this point is known as activation energy. After this point, the energy decreases and the products are formed. The difference between the energy of reactants and products is called the enthalpy change (ΔH). If the energy of products is lower than reactants, the reaction is exothermic. If the energy of products is higher than reactants, the reaction is endothermic. #ChemicalEnergetics #EnergyProfileDiagram #FSC_Chemistry #Chapter6Chemistry #ActivationEnergy #ExothermicReaction #EndothermicReaction #EnthalpyChange #ReactionEnergy #ChemistryDiagrams #BoardExamPrep #FSC_Students
