# A2 Chemistry Coursework - Equilibrium Constant watch

1. I'm sooo stuck on this, I just don't know where to start

Ok so the reaction is
CH3COOH + C2H5OH -> CH3COOC2H5 + H2O (using HCl as a catalyst)

I have 4 mixtures with different starting volumes of each component in. These were left to reach equilibrium and then titrated using NaOH.

I now have no clue as to where to start in determining the equilibrium constant, so any help would be great.

Thanks,

2. Help!!!
3. Can anyone help?!

lol what is the equation for the equilibrium constant - i cant remember, but you should have all the vbariables to go into it - ie, molarity, concentration etc.... cant really help any further than that!! dont know any more

Kc = [CH3COOC2H5][H2O] / [CH3COOH][C2H5OH]

you need the concentrations of them all.
6. I think I'll have to ask my teacher, even though she's the scariest thing alive

I know the formula and things but I can't work out how to work out the concentrations of the components at the start and at equilibrium etc. Never mind, I'll leave it for tonight
