Q
Q: Which of the following is true about the Gibbs free energy change (ΔG)?
Solution:
A negative Gibbs free energy change (ΔG < 0) indicates that the process is spontaneous.
Steps: 4
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: Learn about spontaneous processes. A spontaneous process is one that occurs naturally without needing to be driven by an external force.
Step 3: Know the significance of the sign of ΔG. If ΔG is negative (ΔG < 0), it means the process can happen on its own.
Step 4: Conclude that a negative ΔG indicates that the process is spontaneous, meaning it will occur without additional energy input.
