Question
If a reversible reaction is exothermic in the forward direction, what will happen to the position of equilibrium if the temperature is decreased? Explain your answer using Le Chatelier's Principle.
Answer
If the temperature is decreased, the position of equilibrium will shift towards the exothermicdirection, which is the forward reaction in this case. This shift occurs because the system seeks to produce more heat to counteract the decrease in temperature.
Explanation
This question assesses the ability to apply Le chatelier's Principle to predict the effects of temperature changes on equilibrium. A stronganswer clearly connects the concept of exothermicreactions with the response of the system to temperature changes.
Common mistake
Misunderstanding Temperature Effects
Students often confuse the effects of temperature changes on equilibrium with those on reaction rates, thinking that increasing temperature always increases the rate of reaction rather than affecting the position of equilibrium.
To fix this, students should focus on Le Chatelier's Principle, understanding that increasing temperature favors the endothermic direction of the reaction, which can shift the position of equilibrium rather than simply increasing the reaction rate.
