Q: In a reversible process, the change in Gibbs free energy is equal to:
Solution: In a reversible process at equilibrium, the change in Gibbs free energy is zero.
Steps: 5
Step 1: Understand what a reversible process is. A reversible process is one that can be reversed without leaving any change in the system or surroundings.
Step 2: Know what Gibbs free energy is. Gibbs free energy is a measure of the energy available to do work in a system at constant temperature and pressure.
Step 3: Learn about equilibrium. Equilibrium is the state where the forward and reverse reactions occur at the same rate, and there is no net change in the system.
Step 4: Recognize that in a reversible process at equilibrium, the system is balanced. This means that there is no driving force for the reaction to proceed in either direction.
Step 5: Conclude that because the system is at equilibrium, the change in Gibbs free energy (ΔG) is zero. This means there is no net change in energy available to do work.
