What Does Thermodynamically Stable Mean Thermodynamically favorable but kinetically unfavorable. See how much simpler it looks? What this tells you is that the products are at a lower free energy, or more stable, than the reactants. Because of this, the reactants "want" to be converted into the products. Furthermore, the technology does not produce significant amounts of pollutants. carbon fibres
