Does anyone know of a good source of Gibbs free energy data for compounds of managanese, chromium, silicon and sulfur and oxygen?

RE: thermodynamic data

Heat of formation and coefficients a, b, c and I of free energy written as delatS=-a-2,303*a*logT-2*b*E-3*T+c*E-5*T^(-2) -I for those oxides you can find in Handbook of Chemistry and Physics, The Chemical Rubber Co,lobrary of Congress Card No 13-11056.

RE: thermodynamic data

For Mn, following A+B+CTlogT, depending on the temperature range, use the CRC Handbook of Chemistry and Physics. For others, the same handbook gives the standard values at 298.15 K in kJ/mol.

RE: thermodynamic data

depends on the temperature range you are interested in

Thanks to all. I was able to find the necessary data.

RE: thermodynamic data

If you need similar again try:
