Question
If the enthalpy of the products is lower than the enthalpy of the reactants, what kind of reaction is this?
0 points
- Ectothermic
- Endothermic
- Exothermic
- Esmothermic
Solution
Identifying the Reaction Type
In thermochemistry, understanding the changes in enthalpy (ΔH) during a reaction is crucial for classifying the reaction.
-
Enthalpy of Products vs. Reactants: If the enthalpy of the products is lower than that of the reactants, it implies that the reaction has released energy to the surroundings.
-
Types of Reactions:
- Exothermic: Reactions that release energy (often in the form of heat) and result in products with lower enthalpy than the reactants.
- Endothermic: Reactions that absorb energy from the surroundings, resulting in products with higher enthalpy than the reactants.
-
Conclusion: Given that the enthalpy of the products is lower than that of the reactants, this indicates that energy has been released during the reaction.
Final Answer
The reaction is Exothermic.
