WebQ8 Understanding the free energy change (Δ G) of a reaction is useful to predict if a reaction will occur spontaneously under a given set of conditions: - If Δ G < 0 the reaction is spontaneous - If Δ G > 0 the reaction is not spontaneous c) Use the E cell ∘ value determined in (b) to calculate the standard free energy change (Δ G ∘) of (i) Cell potential … WebThe standard Gibbs free energy change, ΔG°, indicates the thermodynamic favorability of a physical or chemical process. When Δ G ° < 0, the process is thermodynamically favored. For a given process, the value of Δ G ° can be calculated directly from the values of Δ H ° and Δ S ° using the following equation: Δ G ° = Δ H ° - T Δ S °.
