Question: Which of the following is a correct expression for the Gibbs free energy change (ΔG) in terms of enthalpy (ΔH) and entropy (ΔS)?

Options:

Correct Answer: ΔG = ΔH - TΔS

Solution:

The correct expression for Gibbs free energy change is ΔG = ΔH - TΔS, where T is the temperature in Kelvin.

Which of the following is a correct expression for the Gibbs free energy change (ΔG) in terms of enthalpy (ΔH) and entropy (ΔS)?

Step 1: Understand what Gibbs free energy (ΔG) is. It helps us determine if a reaction will occur spontaneously.
Step 2: Know the two important concepts involved: enthalpy (ΔH) and entropy (ΔS).
Step 3: Remember that enthalpy (ΔH) is the heat content of a system, while entropy (ΔS) measures the disorder or randomness.
Step 4: Recognize that temperature (T) must be in Kelvin for the equation to work correctly.
Step 5: Combine these concepts into the formula: ΔG = ΔH - TΔS. This shows how ΔG depends on ΔH, ΔS, and temperature.
