What happens to the position of equilibrium, if a reversible exothermic reaction is subjected to a decrease in temperature?
- The position of equilibrium shifts to the left
-
The position of equilibrium shifts to the right.
- The position of equilibrium remains unchanged
- The reaction stops
The correct answer is: B
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 right, favoring the forward reaction.
