Homework Help: Chemistry

Posted by Miaow on Friday, April 6, 2012 at 11:15pm.

Consider the decomposition of a metal oxide to its elements, where M represents a generic metal:

M2O3 (s) <=> 2M (s) + 3/2 O2 (g)

Given a delta Gf: -770 Kj for the M2O3
0 Kj for the M
0 Kj for the O2

What is the standard change in Gibbs energy for the reaction, as written, in the forward direction?

* I think -770 Kj ??

What is the equilibrium constant of this reaction, as written, in the forward direction at 298 K?

* K is products over reactants which leaves me with 0 ???

What is the equilibrium pressure of O2(g) over M(s) at 298 K?

* I honestly have no idea and am not even sure how to approach this!

Any information is greatly appreciated, thank you!
