Consider the decomposition of a metal oxide to its elements, where m represents a generic metal. m203(> 2m(s) + 3/2 o2(g) info given for gf(kj/mol): m203= -10.60 m(s)=0 o2(g)= 0 1.) what is the standard change in gibbs energy for rxn as written in forward direction? (kj/mol) 2.) what is the equilibrium constant (k) of this rxn, as written in forward direction at 298k? 3.) what is the equilibrium pressure of o2(g) over m(s) at 298k? (atm) for 1.) i got 10.6 kj/mol and this is correct for 2.) i got k= -4.28 and it marked me wrong. now i got an answer of .01387. is this for 3.) i got po2= 0.0016 atm and it marked me don't know how it is wrong. could you check #2 and #3 and tell me what i did wrong and what are the answers .
