If the reaction involves multiple phases the production of a gas typically increases the entropy much more than any increase in moles of a liquid or solid. Best answer a ve because gases are highly random than liquid ΔS S g - S e ve b ve because ions are in more random state in aqueous solution as compared to solid state ΔS s aq - S s ve c -ve because gases are highly more random than solid ΔS S s - S g -ve d Zero. The predicted sign of the entropy change in each reaction are as follows.

Um so were gonna look at some examples here for example if I have any solid and its going to supply meaning it is going to go into that gas phase were going from a solid that is very structure very organized to eat gas which is all over the place. 8-1 additional practice right triangles and the pythagorean theorem envision geometry.
