Minimum Activation Energy (EA) for Endothermic Reaction
Explanation:
- In an endothermic reaction, the products have higher energy than the reactants, resulting in a positive enthalpy change (ΔH) value.
- The activation energy (EA) is the minimum amount of energy required to initiate a chemical reaction.
- The relationship between EA and ΔH can help determine the minimum value of EA for an endothermic reaction.
Comparing EA and ΔH:
- If EA is less than ΔH, it would imply that the reaction could occur without sufficient energy input, which is not possible for an endothermic reaction.
- If EA is equal to ΔH, it would mean that all the energy required for the reaction is supplied at the start, which is not practical for an endothermic reaction.
- If EA is more than ΔH, it ensures that the reaction proceeds by absorbing energy from the surroundings, which is characteristic of an endothermic reaction.
- EA cannot be equal to zero because some energy input is always required to overcome the energy barrier and initiate the reaction.
Conclusion:
- Therefore, in the case of an endothermic reaction, the minimum value of EA will be more than ΔH to ensure that the reaction proceeds by absorbing energy from the surroundings.
