Homework Help: Chemistry

Posted by Jake on Monday, February 4, 2008 at 4:50pm.

Sorry I have one other question that i'm unsure about. for the solution process of A (s)----> A (aq) the teacher demonstrates upon mixing A in H2O that the temp falls from 22 to 5 degrees C. The soluability of this solid is known to be 28g/100g H2O at 30 degrees C. If the solvent (water) temp is increased from 30 degrees C to 60 degrees C, we would expect the soluability of A to:

a. decrease by 1/2
b. increase by 2X
c. not change
d.increase but we cannot determine the value w/o more info
e.decrease but we cannot determine the value w/o more info


i'm not sure how to solve this. any help is much appreciated
