Question

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.

Answer 1

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

Answer 2

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.

Answer 3

Kp = pO2^1/2
Plug in you value of Kp and solve for pO2.Wouldn't pO2 = (Kp)^2

Answer 4

Yes I would be thank you!!
