Question
2CO (g) + O2 <=> 2CO2(g)
Standard molar energies of formation at 288K is -137 kJ/mol for CO and -450 KJ/mol for CO2, find equilibrium constant.
I know that we’re supposed to multiply n to the Gf of products and take the sum and do the same to the reactants. However O2 is not given.

O2 is zero as are all elements in their standard state.

Okay, so I did it. I got 1174 for the delta G rxn and I used that to the other formula. However the next question is saying I’d the 450 was changed to -390. And I got 0 as K.

Liz, you should proof read your posts. You omitted something in that last sentence. If you clarify that please post your work so I can see what you're doing.
