Question

using enthalpy diagrams use the enthalpy diagram to answer this question. is the overall reaction endothermic or exothermic? endothermic exothermic

Explanation:

In an exothermic reaction, the products have lower enthalpy than the reactants. In an endothermic reaction, the products have higher enthalpy than the reactants. If the arrow in the enthalpy - diagram points downwards from reactants to products (as seems to be the case here with the overall change from the top - level to the bottom - level), energy is released and the reaction is exothermic.

Answer:

exothermic
