Homework Help: Chemistry

Posted by Linda on Monday, May 7, 2007 at 2:45pm.

Assuming the dissolution of borax in water is a spontaneous reaction, do you expect the change in enthalpy to be positive or negative or are both signs possible? Explain your answer


A. Neither, enthalpy does not change, the positive entropy for the dissolution, leads to G(G=HTS;G=T(+S).
B. Positive, the absorption of energy creates a spontaneous reaction.
C. Negative, the process of ionization releases energy into solution allowing for a spontaneous reaction.
D. Both, the reaction is spontaneous at high temperatures if H is positive and always spontaneous if H is negative.
E. More information is required.

I would be interested in your thinking on this. And why?
