What happens to the position of equilibrium if a reversible reaction is subjected to a decrease in temperature?
- A. The position of equilibrium shifts to the left
- B. The position of equilibrium shifts to the right.
- C. The position of equilibrium remains unchanged
- D. The reaction stops
Correct Answer: A. The position of equilibrium shifts to the left
Explanation
When the temperature is decreased in a reversible reaction, the equilibrium shifts in the direction that produces heat (exothermic direction). For an exothermic reaction, this means the equilibrium position shifts to the left, favoring the reverse reaction.
