It's sad seeing people actually helping you lol.

and then you dont give brainliest. like ever.

hope that

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.
