Question

When two volatile liquids (X and Y) are mixed, the solution process involves 1. breaking the intermolecular X---X and Y---Y attractions, and 2. forming new X---Y attractions.
Complete this table describing how the relative strengths of these attractive forces affect vapor pressure and enthalpy of solution.
1. X---X, Y---Y, and X---Y are equal
2. X---Y is strongest
3. X---Y is weakest
Raoult's law deviations & deltaHsoln

Answer 1

Where is this table you speak of?

Answer 2

i need to know if its positive negative or zero

Answer 3

It would help if you watched this, if you still can't answer it, I will

Answer 4

i thought it would be zero zero, neg pos, pos neg. but apparently its not the answer.

Answer 5

i watched the video and im gonna assume my first answers are correct (zero, neg, pos) but what is the delta Hsoln? What does that stand for ?

Answer 6

yeah the first column would be zero, negative, positive.

\(H_{soln}\) is the enthalpy of solvation or solution - the change in energy of the bonds when reformed in solution.

Answer 7

well since the first one is all equal it would be zero wouldnt it? so what would the other two be? because when i put in that for the second column it was zero pos neg it said i was wrong.

Answer 8

it would be zero, negative and positive.

For X--Y strongest, there is a net gain of stability in the bonds and so they have less potential energy, likewise, for X-Y weakest but he opposite.

Answer 9

so would this be correct?

Answer 10

yes

Answer 11

ah! thank you so much! i really appreciate it !!

Answer 12

no problem!
