WebJan 15, 2024 · The typical behavior of the Joule-Thomson coefficient can be summarized in Figure 4.5.2. At the combinations of T and p for which μJT > 0 (inside the shaded region), the sample will cool upon expansion. At those p and T conditions outside of the shaded region, where μJT < 0, the gas will undergo a temperature increase upon expansion. WebThe coefficients in the equation tell us that 1 1 mole of \ce {Fe2O3} FeX 2OX 3 reacts with 2 2 moles of \ce {Al} Al, forming 2 2 moles of \ce {Fe} Fe and 1 1 mole of \ce {Al2O3} AlX 2OX 3. We can write the relationship between the \ce {Fe2O3} FeX 2OX 3 and the \ce {Al} Al as …
