Equilibrium law
Read our general notes on Risk Assessment
Chemists use equilibrium constants to predict whether or not reactions tend to go.
It is important to bear in mind that even if a reaction tends to go it may yet go very slowly or not at all.

- I am doing an investigation on partition coefficient of ethanoic acid in water and 2-methylpropan-1-ol. I have to open the tap of the separating funnel occasionally when i am shaking it in order to release pressure in the funnel. Why there is pressure built up in the funnel? I have been asked why it is more efficient to extract a solute with two 25 cm3 portions of solvent rather than with a single 50 cm3 extraction. I don't know how to explain it. 280410
- If a reaction is repeated at a higher temperature and Kc increases greatly, how is the reaction endothermic? 211208
- I'm doing an investigation on the reaction: Ethanoic acid + ethanol -> ethyl ethanoate + water I have to investigate into any aspect of this equation but I have no idea what to do. I can't find any information on it anywhere. I don't know whether it needs a catalyst or what temperature I can expect the best results. I thought I could investigate into the results at different temperatures but I don't know how I would go about this and I'm supposed to get in a list of apparatus and chemicals before the end of next week. I don't want anybody to do the work for me, I just would like a bit of help please! 220908
