Question

swyk: energy diagrams
potential energy
reaction coordinate
the energy diagram above represents an reaction, meaning that energy is during this chemical reaction.

Explanation:

Step1: Analyze energy of reactants and products

In an exothermic reaction, the energy of the products is lower than the energy of the reactants. In an endothermic reaction, the energy of the products is higher than the energy of the reactants. Looking at the diagram, the potential - energy of the products (right - hand side) is lower than that of the reactants (left - hand side).

Step2: Determine energy change

Since the products have lower energy, energy is released during the reaction.

Answer:

Exothermic; released
