What are the units? -6.00 what?
1.
dHrxn = (n*Gf products)-(n*dGf reactants).
2.
dG = -RTlnK
3.
Kp = pO2
Consider the decomposition of a metal oxide to its elements, where M represents a generic metal.
M203(s)<---> 2M(s) + 1/2 O2(g)
info given for Gf(kJ/mol):
M203= -6.00
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)
