Q
Q: In a reversible process, the change in Gibbs free energy (ΔG) is:
Solution:
In a reversible process, the change in Gibbs free energy (ΔG) is zero at equilibrium.
Steps: 5
Show Steps
Step 1: Understand what Gibbs free energy (ΔG) is. It is a measure of the energy available to do work in a system.
Step 2: Know that a reversible process is one that can go forward and backward without losing energy.
Step 3: Recognize that equilibrium is the state where the forward and reverse processes occur at the same rate.
Step 4: At equilibrium, there is no net change in the system, meaning the system is stable.
Step 5: Since there is no change in the system at equilibrium, the change in Gibbs free energy (ΔG) is zero.
