← ScienceWhich effect occurs when endothermic reaction temperature decreases within a closed system?
A)Equilibrium position shifts toward reactants✓
B)Forward reaction rate constant increases
C)Activation energy of reverse reaction lowers
D)Total system energy remains constant
💡 Explanation
When an endothermic reaction's temperature decreases, the equilibrium position shifts toward the reactants because Le Chatelier's principle dictates the system will counteract the temperature change by favoring the heat-absorbing (reactant) side. Therefore reduced yield, rather than changes in reaction rates or unchanged total system energy results without intervention.
