Which of the following statements is true regarding Gibbs Free Energy?
ΔG is always positive for spontaneous processes.
ΔG = ΔH - TΔS.
ΔG can never be negative.
ΔG is independent of temperature.
The correct equation for Gibbs Free Energy is ΔG = ΔH - TΔS, which relates enthalpy, entropy, and temperature.

Q: Which of the following statements is true regarding Gibbs Free Energy?
Solution: The correct equation for Gibbs Free Energy is ΔG = ΔH - TΔS, which relates enthalpy, entropy, and temperature.
Steps: 5
Step 1: Understand what Gibbs Free Energy (ΔG) is. It helps predict if a reaction will happen spontaneously.
Step 2: Learn the components of the Gibbs Free Energy equation: ΔG = ΔH - TΔS.
Step 3: Identify what each symbol means: ΔH is the change in enthalpy (heat content), T is the temperature in Kelvin, and ΔS is the change in entropy (disorder).
Step 4: Recognize that a negative ΔG means the reaction is spontaneous, while a positive ΔG means it is not.
Step 5: Remember that the equation shows how enthalpy and entropy affect the spontaneity of a reaction.
