?The data in Table 10.3 are experimental values of \(H^{E}\) for binary liquid mixtures
Chapter 10, Problem 10.33(choose chapter or problem)
The data in Table 10.3 are experimental values of \(H^{E}\) for binary liquid mixtures of 1,2-dichloroethane(1) and dimethyl carbonate(2) at 313.15 K and 1(atm).
(a) Determine from the data numerical values of parameters a, b, and c in the correlating equation:
\(H^{E}=x_{1} x_{2}\left(a+b x_{1}+c x_{1}^{2}\right)\)
(b) Determine from the results of part (a) the minimum value of \(H^{E}\). At what value of \(x_{1}\) does this occur?
(c) Determine from the results of part (a) expressions for \(\bar{H}_{1}^{E} \text { and } \bar{H}_{2}^{E}\). Prepare a plot of these quantities vs. \(x_{1}\), and discuss its features.
