during a reaction, δh for reactants is −750 kj/mol and δh for products is 920 kj/mol. which statement is correct about the reaction?
it is endothermic because the energy required to break bonds in the reactants is less than the energy released when the products are formed.
it is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed.
it is exothermic because the energy required to break bonds in the reactants is less than the energy released when the products are formed.
