does changes in solubility between solute and solvent, just mean that the rate at which solute co2(gas) is dissolved by solvent to form co2(aq) is = to rate at which c02(aq) gains eenrgy from collitions to leave dissolved state or what? I need siome clarity.

chemistry
carbon dioxide collide with the liquid solvent and enters its dissolved states? so what does this have to do with solubility equillibrium.
August 6, 2009

chemistry
Equillibrium, an example given by my textbook confused me. First it shows a reaction inside a soft drink: co2(g)--><--co2(aq) but than it says the reaction inside a soft drink would involve solubility equillibrium because it involves a change in solubility between ...

Chemistry
Since decomposition is an endergonic reaction. Does this mean it's reverse reaction synthesis is exothermic?

5. addinf water to a equillbrium system will make it more dilute and increase the volume but decrease pressure so system will shift in direction which produces more ions?

1.If a container that is 1L has 1 mol of solid NACL , if you add more nacl will the concentration of solid increase? it should? because if you increase it to two mols it will become 2 mol/l right? so in a equillibrium system like nacl(s)--><---na+ + cl- if you increase ...
