A student made a sketch of a potential energy diagram to representing endothermic reaction . Explain, using complete sentences, why the diagram made by the student is correct or incorrect. Be sure to also explain what the value of x and y represent

that graph is incorrect

Explanation:

The total potential energy of the system increases for an endothermic reaction as the system absorbs energy from the surroundings. The graph being shown represents a exothermic reaction because the total potential energy decreases at the end. In this graph, the x represents the reactants and the y represents the products. For an endothermic reaction, the y should represent the reactant and the x should represent the products. Just put that into complete sentence and you should be good. If you have any question, ask.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
