Answer: The reaction will shift in left or backward direction.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
As the given reaction is exothermic as the heat is released in the reaction. When the temperature is raised , the reaction will shift in a direction where temperature is decreasing and that is the reverse reaction which is endothermic in nature.
Thus the reaction will shift in left or backward direction.
