Answer:
Exothermic reaction
Explanation:
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise
The potential energy diagram for a reaction starts at 180 kJ and ends at 300 kJ. the type of reaction does the diagram best represent exothermic reaction.
An exothermic reaction would be one in which heat energy is emitted. Exo stands for "evolve out." The term "thermos" refers to a container that holds heat. The term "exothermic" refers to a process in which heat is produced. In general, an exothermic reaction is one in which heat is released as a byproduct.
Therefore, the reaction diagram will represent exothermic reaction.
