Question

4. The graph below shows the partial pressure of one component of a binary mixture as a function of its mole fraction (in the solution). a) Does the graph show component 1 or component 2? b) Circle and label the region where Raoult's law is a reasonable model. c) Circle and label the region where Henry's law is a reasonable model. d) On the same plot, (There are an infinite number of correct responses here. Unfortunately, there are also an infinite number of incorrect ones. Choose any one of the former.) e) Indicate P, and k1 on the graph. draw a reasonable graph of the partial pressure of the other component ative deviations from Raoult's law? g) Would you expect AmaH to be less than, equal to, or greater than zero? Why? Real Ideal 1

Explanation / Answer

a) Graph shows component 1 pressure vs molefraction

b) component reaching molefraction of 1 is reasonable model for raoults law because raoults law applicable at ideal solutions only.

c)as above mentioned henry's law also applicable as x1->1.

f)this graph is positively deviating from raoults law.

g) del H must be less than 1.
