Question: In a reaction at equilibrium, if the temperature is increased and the reaction is exothermic, what will happen to the equilibrium position?

Options:

  1. Shift to the right
  2. Shift to the left
  3. No change
  4. Equilibrium constant increases

Correct Answer: Shift to the left

Solution:

For an exothermic reaction, increasing the temperature shifts the equilibrium position to the left, favoring the reactants.

Questions & Step-by-Step Solutions

In a reaction at equilibrium, if the temperature is increased and the reaction is exothermic, what will happen to the equilibrium position?
  • Step 1: Understand what an exothermic reaction is. It is a reaction that releases heat.
  • Step 2: Know that in a reaction at equilibrium, the system is balanced between reactants and products.
  • Step 3: Recognize that increasing the temperature adds heat to the system.
  • Step 4: Apply Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
  • Step 5: Since the reaction is exothermic, adding heat will cause the equilibrium to shift to the left, favoring the reactants.
  • Le Chatelier's Principle – This principle states that if a system at equilibrium is subjected to a change in temperature, pressure, or concentration, the system will adjust to counteract that change and restore a new equilibrium.
  • Exothermic Reactions – In exothermic reactions, heat is released, and increasing temperature can shift the equilibrium towards the reactants.
