Consider the decomposition of a metal oxide to its elements where m represents a generic metal.
M2O(s)<->2M(s)+1/2O2(g)

the delta G is 10.30

I need to find K and PressureO2 at 298K I know the equations but i keep getting the answer wrong could you please help me. Could you show me all of the work.

It's much easier for you to show your work and let us critique it.

I had to calculate delta G which came out to be 10.30 then i had to solve for Kp so I used the equation
DeltaG=-RT(ln Kp) then I got .01565, now im trying to calculate the equilibrium pressure of O2 and that has me stumped.
Answered by DrBob222
Kp = pO2^1/2
Plug in you value of Kp and solve for pO2.Wouldn't pO2 = (Kp)^2

Yes I would be thank you!!
