Question: Which of the following statements is true about Gibbs Free Energy?
Options:
ΔG is always positive for spontaneous processes.
ΔG = ΔH - TΔS.
ΔG can never be zero.
ΔG is independent of temperature.
Correct Answer: ΔG = ΔH - TΔS.
Solution:
The correct equation for Gibbs Free Energy is ΔG = ΔH - TΔS, which relates enthalpy, entropy, and temperature.

Questions & Step-by-Step Solutions
Which of the following statements is true about Gibbs Free Energy?
Step 1: Understand what Gibbs Free Energy (ΔG) is. It helps predict if a reaction will happen spontaneously.
Step 2: Learn the equation for Gibbs Free Energy: ΔG = ΔH - TΔS.
Step 3: Identify the components of the equation: 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.
