Problem

The following equilibrium pressures were observed at a certain temperature for the reaction

N2(g) + 3H2(g) ⇌ 2NH3(g)

PNH3 = 3.1 x 10 -2 atm

PN2 = 8.5 x 10 -1 atm

PH2 = 3.1 x 10 -3 atm

Calculate the value for the equilibrium constant Kp at this temperature.

If PN2 = 0.525 atm, PNH3 = 0.0167 atm, and PH2 = 0.00761 atm, does this represent a system at equilibrium?
