equilibrium question?

Question

When .100 moles of gaseous N2 and .100 moles of gaseous H2 are put into a .500 L container at 250°C, the following reaction occurs and reaches equilibrium.
N2 (g) + 3 H2 (g) <--> 2 NH3 (g)
The total pressure in the flask at equilibrium is 1.52 atm. Calculate K and KP (K Presssure) for this reaction.

Answer 1

Initial pressure = .2*0.0821*523/.5 = 17.175 atm

Now apply Le Chatelier.
