According to my teacher in my chemistry lesson, the equilibrium constant has different units depending on how many moles of reactant and product there are. But the idea of a constant which changes it's units depending on the situation seems a bit dodgy to me, especially as it seems to be related to ratios, and I though ratios are meant to be dimensionless.
Also, the units seem to be based on which power the concentration is to, but seeing as that depends on the moles of the reactants, which is a variable in itself, I would have thought it wouldn't change the units, so I think it is dimensionless. I did some research on this, and some websites confirm my idea, some confirm my teacher's. (I'm going with my teacher's viewpoint for the sake of the exam, anyway, but I want to know which is right.)
So which is true? Is it dimensionless, or do the units change depending on the situation?
(If this would be more appropriate in the homework help section, please move it.)
