Answer: equilibrium shifts in either right or left side
Explanation: it is explained based on Le Chatlier's principle, it states that if we change any parameters of system then equilibrium shifts in a direction to cancel that change.
Here based on temperature, we can discuss under two classes of Reactions
Exothermic and Endothermic reaction
If a reaction is Exothermic, it release heat (means that occur at less temperature) if we increase the temperature then equilibrium shifts towards left side(reverse reaction occurs)
In the case of endothermic reaction, if temperature is increased equilibrium shifts towards right side, favors products.
