Question

Quizplus · Accepted Answer

An increase in temperature usually leads to an increase in the equilibrium constant for an endothermic reaction. This is because the reaction absorbs heat from the surroundings, which favours the formation of products at higher temperatures. Therefore, at 2500 K, the equilibrium constant for the given reaction will be greater than 5.0 × 10^-4. The correct choice is A.
