WebbThe standard free energies of formation can be used to calculate the free energy change of any reaction under standard conditions. Calculate the free energy change for the formation of methanol from carbon monoxide and hydrogen gas: CO (g) + 2H 2 (g) CH 3 OH ( l ) Correct! Remember to include units with your answer. That is incorrect. Try again. WebbThe Gibbs free energy change is Δ G = Δ H − T Δ S. In this case the Gibbs free energy change is zero because the water and steam are in equilibrium, and no useful work can be extracted from the system (other than work done against the atmosphere). crunch fitness citrus heights
