The reaction diagram illustrates what type of reaction?
Enthalpy
Reaction Coordinate

Answer:
The answer to your question is Endothermic reaction
Explanation:
Endothermic reactions are reactions that absorbe energy from the environment.
All the reactions that needs heat to proceed are endothermic, example: photosynthesis, reactions in the laboratory that are heated, heat our meals.
This is an endothermic reaction because the enthalpy of the products is higher than the enthalpy of the reactants,
