The vapour pressure of water is 0.04 atm at . The free energy change for the following process is — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

At the exact specified pressure (0.04 atm) and temperature ($27^\circ\text{C}$), the liquid and gaseous phases of water reside in dynamic physical equilibrium. Because the system is at equilibrium, the change in Gibbs free energy ($\Delta G$) evaluates inherently to zero.
