1. ok so we ignore [h2o] in dissociation constant but we include it in the expression for esterification
but why is that?
and what about hydrolysis?
2) here’s a reaction:
A(l) + B(l) –> C(g) + D(l)
textbook shows that the equilibrium constant expression for this reaction is K=[C]
why isn’t it K=([C][D])/([A][B])? would it be like that if A, B and D were (aq)?
3) let’s take dissociation constant for a weak HX acid – the [HX] is the total concentration of the acid or it’s the concentration of undissociated HX molecules?
