What is the free energy change, Δ G, when 1.0 mole of water at 100°C and 1 atm pressure is converted — Thermodynamics and Thermochemistry Chemistry Question
Question
What is the free energy change, Δ G, when 1.0 mole of water at 100°C and 1 atm pressure is converted in to steam at 100°C and 1 atm pressure?
Answer: D
💡 Solution & Explanation
At 100°C and 1 atm, liquid water is in physical equilibrium with gaseous steam. For any phase change at equilibrium, the change in Gibbs free energy is zero (Δ G = 0).
