Question: If the temperature of an exothermic reaction at equilibrium is increased, what is the expected effect on the equilibrium position?

Options:

  1. Shifts to the right
  2. Shifts to the left
  3. No effect
  4. Reaction rate increases

Correct Answer: Shifts to the left

Solution: 

For an exothermic reaction, increasing the temperature shifts the equilibrium to the left, favoring the reactants, as the system attempts to absorb the added heat.

Questions & Step-by-Step Solutions

If the temperature of an exothermic reaction at equilibrium is increased, what is the expected effect on the equilibrium position?
  • Step 1: Understand that an exothermic reaction releases heat.
  • Step 2: Recognize that at equilibrium, the reaction can go in both directions: forward (producing products) and backward (producing reactants).
  • Step 3: Know 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.
  • Step 6: Conclude that the expected effect of increasing the temperature is a shift towards the reactants.
  • Le Chatelier's Principle – This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
  • Exothermic Reactions – In exothermic reactions, heat is released, and increasing temperature can shift the equilibrium towards the reactants.
