Which phenomenon limits theoretical yield in exothermic reversible reactions at elevated temperatures?

💡 Explanation

When temperature increases in exothermic reversible reactions, the equilibrium shifts towards reactants via Le Chatelier's principle, because the reverse endothermic reaction is favored, altering the Boltzmann distribution. Therefore product yield decreases, rather than increased activation energy, collision frequency, or catalyst poisoning which are influenced by different mechanisms.
