Question 15

Chemical Equilibrium

In the reaction M + N ⇌ P; ΔH = +Q kJ. Which of the following would increase the concentration of the product?

  1. A.Decreasing the concentration of N
  2. B.Increasing the concentration of P
  3. C.Adding a suitable catalyst
  4. D.Decreasing the temperature
  5. E.Increasing the temperature
Show the answer and explanation

Answer: E (Increasing the temperature)

Explanation

ΔH is positive, so the forward reaction is endothermic. Raising the temperature shifts the equilibrium to the right, making more P.
