Question 21

Chemical Equilibrium

If an equilibrium reaction has ΔH > 0, the reaction will proceed favourably in the forward direction at

  1. A.high temperature
  2. B.any temperature
  3. C.low temperature
  4. D.minimum temperature.
Show the answer and explanation

Answer: A (high temperature)

Explanation

ΔH > 0 means the forward reaction is endothermic, and by Le Chatelier's principle heating favours the endothermic direction.
