Question 35

Energy Changes

Which of these equations shows that a reaction is in equilibrium?

  1. A.ΔG = ΔH − TΔS
  2. B.ΔG < O
  3. C.ΔG = O
  4. D.ΔG > O
Show the answer and explanation

Answer: C (ΔG = O)

Explanation

At equilibrium there is no driving force in either direction, so the free energy change ΔG is zero.
