Hi, I am new to the forum.
Probably will be coming here a lot though!
Anyways I have a problem that I need help with.
If someone can just get me started and maybe break down the problem into what I need to do
I would appreciate it!

-----------------------------------------
Some NO has was placed into a 2.00 L container until the pressure was 0.650 atm.
The following equilibrium was obtained:
 
2NO(g) <--> N2(g) + O2(g)

The equilibrium pressure of N2 was found to be 5.25*10^-2 atm.
Calculate the Kp for this reaction.
-----------------------------------------

If anyone can help me it would be great. I really need to do this problem.

Thanks.

Yeah, but you should show your attempts first.
But I think you can see that N₂ and O₂ will have the same pressure because they have the same moles. Use the equation:
P_(total) = P_(parts)
You can calculate the moles of NO then you'll calculate K_P
