Gibbs Free Energy – The relationship between enthalpy (ΔH), entropy (ΔS), and temperature (T) to determine the spontaneity of a process using the equation ΔG = ΔH - TΔS.
Units of Measurement – Understanding the units of ΔH (kJ) and ΔS (kJ/K) and ensuring consistency in calculations.
Temperature in Kelvin – Recognizing that temperature must be in Kelvin for thermodynamic calculations.
