In which scenario would ΔG be equal to ΔH?

In which scenario would ΔG be equal to ΔH?

Step 1: Understand what ΔG means. ΔG is the change in free energy of a system.
Step 2: Understand what ΔH means. ΔH is the change in enthalpy, or total heat content, of a system.
Step 3: Know what ΔS means. ΔS is the change in entropy, which measures the disorder or randomness in a system.
Step 4: Recognize the relationship between ΔG, ΔH, and ΔS. The equation is ΔG = ΔH - TΔS, where T is the temperature in Kelvin.
Step 5: Identify when ΔG equals ΔH. This happens when ΔS is zero, meaning there is no change in disorder.
Step 6: Conclude that if there is no change in disorder (ΔS = 0), then ΔG will equal ΔH.
