Question

This problem is going to walk you through using the Two- Parameter Margules equation to calculate the bubble temperature. Consider a binary mixture of component (1) component (2). Vapor pressures using log10(P(mmHg)) A B/(T(Celsius) C) for component (1) and component (2) are tabulated below. component (1) component (2) A 7.44 7.26475 B 1843.12 1434.148 C 230.22 246.721 (a) What is the vapor pressure (mmHg) of component (1) at 24°C? 1.548 You are correct. Previous Tries Your receipt no. s 150-7369 (b) What is the vapor pressure (mmHg) of component (2) at 24°C? 92.73 You are correct. Previous Tries Your receipt no. s 150-7491 (c) An experiment with a mixture of component (1) and component (2) was performed, resulting in A12 0.8 and A21 0.96. At a mole fraction of component (1) of x(1) 0.13, what is Y1? Submit Answer Tries 0/4 (d) At a mole fraction of component (1) of x(1) 0.13, what is 12?

Explanation / Answer

Vapour pressure of component 1 =log[7.44-1843.12/297+7.2647]=log(8.498)=0.929

Vapour pressure of component 2=log[7.2647-1434.148/297+246.72]=log(249.155)=2.17
