Hello,

I was looking on the web for a comprehensive list of equilibrium constants, as a function of temperature, for simple reactions such as

2 SO2 (g) + O2(g)  = 2 SO3(g)

Can you suggest a site or handbook where this information can be found ? That would be great !!
The CRC handbook wasn't helpful in this respect.

Thanks in advance

Use thermodynamic data tables (H, S) to calculate  :delta: G, then use  :delta: G = -RT ln(K). Still, that's only approximation.
