WebFree energy (delta G) is a measurement of the enthalpy and entropy of a chemical reaction. If delta G is negative, a reaction is spontaneous and will occur; if delta G is positive a reaction is nonspontaneous. 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 …
