Equilibrium constant decreases as the temperature___________________?
Correct answer: A. Increases, for an exothermic reaction
- A. Increases, for an exothermic reaction
- B. Decreases, for an exothermic reaction
- C. Increases, for an endothermic reaction
- D. None of these
Explanation
For an exothermic reaction, heat behaves like a product, so raising temperature shifts equilibrium toward reactants and lowers the equilibrium constant. This follows directly from the van't Hoff relation.
