Q
Q: Which of the following is true about the Gibbs free energy change (ΔG) for a spontaneous process?
Solution:
For a spontaneous process, the Gibbs free energy change (ΔG) is less than 0 (ΔG < 0).
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: 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 relationship between ΔG and spontaneity. For a process to be spontaneous, the change in Gibbs free energy (ΔG) must be negative.
Step 4: Remember the rule: If ΔG < 0, the process is spontaneous. This means that the system is losing energy and can do work.
Step 5: Conclude that for a spontaneous process, ΔG is less than 0.
