This reaction is endothermic.
Predict the effect (shift right, shift left, or no effect) of these changes.
(a) increasing the reaction temperature
(b) decreasing the reaction temperature
Solution: Here, we are going to predict the effect of the changes in the given reaction.
Le Chatelier’s principle states that, a change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner so as to reduce or to counteract the effect of the change.
For an exothermic reaction, increase in temperature decreases the value of the equilibrium constant and for an endothermic reaction, the equilibrium constant increases as the temperature increases.
Since, the given reaction is endothermic, therefore,
- Increasing the reaction temperature will shift the equilibrium to the right.
- Decreasing the reaction temperature will shift the equilibrium to the left.
