Final answer:
The term in the Gibbs free energy equation that denotes enthalpy is ΔH (enthalpy change), which is part of the equation ΔG = ΔH - TΔS within the field of thermodynamics in Chemistry. Option C
Step-by-step explanation:
The term in the Gibbs free energy equation that denotes enthalpy is ΔH (enthalpy change). The Gibbs free energy equation is represented as ΔG = ΔH - TΔS, where ΔG is the Gibbs free energy change, ΔH is the enthalpy change, T represents the absolute temperature in Kelvin, and ΔS is the entropy change.
The equation indicates how the free energy change (ΔG) for a process is related to enthalpy, entropy, and temperature, with enthalpy being a measure of the total heat content of a system. The unit for ΔH is typically kilojoules per mole (kJ/mol). Option C
