Sometimes when energy is used no work is done
WebJul 20, 2024 · The minimum work that must be done is given by Δ G. As an example of the utility of this interpretation of Δ G, consider the recovery of Al from Al 2 O 3 ore: Al 2 O 3 → 2 Al + 3 2 O 2 Δ G m ∘ ( 298 K) = 1576.4 kJ mol. The positive Δ G tells us that at least 1576.4 kJ of work must be done on 1 mol Al 2 O 3 to effect this change. WebDec 7, 2009 · 3,967. 327.
