    Standard Enthalpy of Formation - Exothermic?

    Hello, I have a conceptual question about enthalpies of formation I hope you can assist me with. Given that the enthalpy of reaction is typically negative, does that suggest that the product formed is lower in energy than the reactants? For example, O2 + 1/2 C (graphite) --> CO2. ΔH f...
