What happens in all solutions? A. Liquids are stirred together rapidly

B. two gasses are in the same space

C. Two substances mix evenly without reacting

D A solid mixes with a liquid and slowly settles out

I think D

Explanation:

one substance called the solute "dissolves" into another substance called the solvent

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
