Q: What is the significance of the Gibbs free energy change (ΔG)?
Solution: ΔG indicates whether a reaction is spontaneous (ΔG < 0) or non-spontaneous (ΔG > 0).
Steps: 4
Step 1: Understand that Gibbs free energy (ΔG) is a measure of energy available to do work in a chemical reaction.
Step 2: Know that if ΔG is less than 0 (ΔG < 0), the reaction can happen on its own without needing extra energy. This is called a spontaneous reaction.
Step 3: If ΔG is greater than 0 (ΔG > 0), the reaction needs energy to happen and will not occur on its own. This is called a non-spontaneous reaction.
Step 4: Remember that ΔG helps predict the direction of a reaction and whether it will occur naturally.
