Consider the reaction pathway graph below. which method would provide evidence to support the inference that this is an exothermic reaction?
add a and c
add e and d
subtract a from c
subtract e from d

subtract E from D

Explanation:  Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The energy is absorbed in the form of heat and for the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is less than the energy of the reactants. The energy is released in the form of heat and for the reaction comes out to be negative.

E- represents energy of reactants

F- represents energy of products

As < thus

and the reaction is exothermic.
