Question on: SS3 Chemistry - Chemical Equilibrium
An endothermic reaction is at equilibrium in a closed container. If the temperature of the system is increased, what will be the effect on the equilibrium position?
The reaction will shift to favour the exothermic direction
The reaction will shift to favour the endothermic direction
The equilibrium position will remain unchanged
The reaction will shift in the direction that consumes heat
An endothermic reaction absorbs heat from the surroundings. According to Le Chatelier's Principle, if the temperature of the system is increased, the system will shift in the direction that absorbs heat to counteract the temperature increase. Therefore, the reaction will shift to favour the endothermic direction, which absorbs more heat to restore equilibrium.
