An reaction results when the energy released by the formation of products is greater than the energy required to break the bonds in the reactants.

Exothermic

Explanation:

An exothermic reaction results when the energy released by the formation of products is greater than the energy required to break the bonds in the reactants.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
