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'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
- If the reversible reaction: 2H2O(g) --> 2H2(g) + O2(g) occurs at 1 atm pressure and 20% of the steam is converted to hydrogen and oxygen, how do we find the equilibrium partial pressures (in atm) of the components of the equilibrium? 140408
- I recently came across a question in a past examination paper which did not resemble any of the examples I had previously worked out. The question concerns homogeneous pressure equilibria, specifically the equilibrium reaction of the Haber process, N2(g) + 3H2(g) -> 2NH3(g). The question read as follows: nitrogen and hydrogen are introduced into a vessel of fixed volume, each of partial pressure 2 atm. The vessel is maintained at 500 K when the gases react to form an equilibrium mixture having a total pressure of 3.6 atm. Estimate the partial pressures of all gases at equilibrium, and deduce a value for Kp for the equilibrium at 500 K. Any help with shedding some light on how to go about tackling this question would be much appreciated. 130408
