Question: Which of the following is true about the Gibbs free energy change (ΔG)?

Options:

Correct Answer: ΔG < 0 indicates a spontaneous process

Solution:

A negative Gibbs free energy change (ΔG < 0) indicates that the process is spontaneous.

Which of the following is true about the Gibbs free energy change (ΔG)?

Which of the following is true about the Gibbs free energy change (ΔG)?

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.
