Question
When the temperature of an endothermic reaction is decreased, what is the expected effect on the equilibrium position (A-level cue 12a2c590 focus)
Answer
The position of equilibrium shifts to the left, favoring the reactants. This answer is anchored to Equilibrium and Le Chatelier's principle. This version is uniquely anchored to Equilibrium and Le Chatelier's principle. Retrieval anchor: A-level cue 12a2c590.
Explanation
The position of equilibrium shifts to the left, favoring the reactants. This answer is anchored to Equilibrium and Le Chatelier's principle. is correct because it supports the objective: Use Le Chatelier's principle to predict the effect of temperature changes.. The reasoning stays within Equilibrium and Le Chatelier's principle and avoids drifting into a similar A-Level Chemistry idea. This version is uniquely anchored to Equilibrium and Le Chatelier's principle. Retrieval anchor: A-level cue 12a2c590.
Common mistake
Temperature Change Misunderstanding
Students often believe that increasing temperature always shifts the equilibrium to the right, regardless of the reaction type.
Understand that increasing temperature shifts the equilibrium position in the direction that absorbs heat (endothermic direction) for a given reaction. For exothermic reactions, increasing temperature shifts the equilibrium to the left, reducing product yield.
