if the temperature of water decreases...

[faerielynx]

if the temperature of water decreases, what happens to the enthalpy? Is it going to to be H>0 or H<0, endothermic or exothermic? I'm doing destroyer and #75 and #41 is kinda givin me mixed results. So which is it?...

Oh, one more thing... when past test takers say to know sn1, sn2, E2 and E1 rxns for organic, what exactly should i know?... can anyone be more specific...?

the water problem kind of depends on what reaction is taking place. However if the liquid is decreasing in temp then it is probably endothermic because there is no heat given off. All the heat is absorbed into bonds, ect.
