Answer:
Exothermic
Step-by-step explanation:
Well as we can, see the energy decreases when it changes from reactant to product.
Endothermic reactions involve the absorption of energy from the surroundings (meaning there would be in an increase in energy)
Exothermic reactions involve the energy being released into the surroundings (meaning there would be a lost in energy)
Therefore, the reaction is exothermic.
