Question

The vapor pressure of component A for a binary mixture (A and B) is given by the equation below:

PA = 6.1xAe-0.65xB + 1.6xB*xB

What is henry's law constant for component A?

Answer 1

Henry's law:

C = k*P

k - henry's law constant

x_A = k * (6.1x_A-0.65x_B + 1.6x_B*x_B)

x_A = k * (6.1x_A-0.65(1-x_A) + 1.6*(1-x_A)²)

$k=\frac{x_A}{6.1x_A-0.65(1-x_A) + 1.6*(1-x_A)^2}$
