  • Modified Raoult’s Law and Excess Gibbs Energy

    In Section 10.7 we demonstrated that deviations from Raoult’s law were manifested by changes in the bubble line and thus characterized positive and negative deviations. With a purely mathematical perspective for modeling the behavior, we could develop a “correction” to Raoult’s law as illustrated in Fig 11.1. Figure 11.1. P-x-y diagram for isopropanol water at 30°C illustrating the…
