Answer:
Here's what I get
Explanation:
Your graph should resemble the one below.
The ethanol and oxygen molecules must receive enough energy (perhaps from a match flame) to get over an activation energy barrier (Eₐ).
The products are lower in energy than the reactants, so the difference in energy is given off as heat (ΔH).
The overall energy change is
ΔH = Energy of products - energy of reactants
The products are lower in energy than the reactants, so the combustion of ethanol is exothermic.
