Question

Select the correct answer.

Answer 1

H= energy of product minus energy of reactant

H is endothermic and positive when heat is absorbed

H is exothermic and negative when heat is released

You forgot to attach the diagram but I have an idea of what it might look like. So since the energy of reactant is at a lower level and energy of product is at a higher level, the reaction will be positive.

Answer: C. The difference of the energy of the reactants and the energy of the products.
