Question: For the exothermic reaction A + B β‡Œ C + heat, what will happen if the temperature is increased? (2020)

Options:

  1. Equilibrium will shift to the right
  2. Equilibrium will shift to the left
  3. No change in equilibrium
  4. Equilibrium will shift to the center

Correct Answer: Equilibrium will shift to the left

Exam Year: 2020

Solution:

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

Questions & Step-by-Step Solutions

For the exothermic reaction A + B β‡Œ C + heat, what will happen if the temperature is increased? (2020)
  • Step 1: Understand that the reaction A + B β‡Œ C + heat is exothermic, meaning it releases heat.
  • Step 2: Recognize that increasing the temperature adds heat to the system.
  • Step 3: Apply Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
  • Step 4: Since we added heat, the system will try to absorb this extra heat.
  • Step 5: To absorb the added heat, the equilibrium will shift to the left, favoring the reactants A and B.
  • 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.
