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
설명
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.
