Transcribed Image Text:Liquid mixtures of n-octanol (1) and n-decane (2) at atmospheric pressure of 300 K
The heat changes data resulting from mixing in temperature were measured and the following equation
obtained:
▲H = X₁X₂(A + B(X₁ - X₂)) J/mol
Here A = 2476; B = 1456.2
a) Calculate the partial properties of H₁ and H2 for this binary mixture based on 0.1 step increment in the
range 0-1 (0, 0.1, 0.2, ..., 0.9, 1.0) against the mole fraction X1 and using an appropriate computer
program (Python-Matplotlib module or MATLAB) Plot the graph against x₁ (the two partial
properties must also be included in the same graph).
b) Determine the equations that will make the H₁ and H2
partial properties of this binary mixture a function of the
quantity Calculate the a, b, c and d coefficients in the equations
using the tools below.
1. Using Excel
2. Using a computer program (polyfit in Python-Numpy module or
MATLAB)
DATA: H₁ = 1019.8. ;
H2 = 3992.2
