For a reaction at equilibrium, the change in Gibbs free energy (ΔG) is equal to:
ΔH - TΔS
0
ΔS - TΔH
ΔH + TΔS
At equilibrium, the change in Gibbs free energy (ΔG) is zero, indicating that the system is at maximum entropy.

Q: For a reaction at equilibrium, the change in Gibbs free energy (ΔG) is equal to:
Solution: At equilibrium, the change in Gibbs free energy (ΔG) is zero, indicating that the system is at maximum entropy.
Steps: 5
Step 1: Understand what equilibrium means in a chemical reaction. It is the point where the forward and reverse reactions occur at the same rate.
Step 2: Know that Gibbs free energy (ΔG) is a measure of the energy available to do work in a system.
Step 3: Realize that at equilibrium, the system has reached a state where there is no net change in the concentrations of reactants and products.
Step 4: Recognize that when a system is at equilibrium, the change in Gibbs free energy (ΔG) is zero. This means that the system is stable and not moving in either direction.
Step 5: Understand that a ΔG of zero indicates that the system is at maximum entropy, meaning it is in the most disordered state possible under the given conditions.
