Answer;

Water has the highest normal boiling point and methanol on the other hand has the lowest boiling point.

Explanation;

-The normal boiling point is the temperature in which the vapor pressure of a liquid becomes equal to atmospheric pressure.If the inter-molecular forces are small, the liquid has a high vapor pressure. Little heat energy will have to be added to separate the molecules, so the boiling point will be low.

-Boiling points and equilibrium vapor pressure are inversely proportional, because less heat is required to raise vapor pressure to reach atmospheric pressure.

-Therefore, since water has the lowest vapor pressure, water it has the highest boiling point and since methanol has the highest vapor pressure it has the lowest boiling point.

A sealed 1.0L flask is filled with 0.500 mols of I_2 and 0.500 mols of Br_2. When the container achieves equilibrium the equilib
DochEvi [55]

Answer:

[IBr] = 0.049 M.

Explanation:

Hello there!

In this case, according to the balanced chemical reaction:

I_2+Br_2\rightarrow 2IBr

It is possible to set up the following equilibrium expression:

K=\frac{[IBr]^2}{[I_2][Br_2]} =0.0110

Whereas the the initial concentrations of both iodine and bromine are 0.50 M; and in terms of x (reaction extent) would be:

0.0110=\frac{(2x)^2}{(0.50-x)^2}

Which can be solved for x to obtain two possible results:

x_1=-0.0277M\\\\x_2=0.0245M

Whereas the correct result is 0.0245 M since negative results does not make any sense. Thus, the concentration of the product turns out:

[IBr]=2x=2*0.0249M=0.049M

Regards!
