The following equilibrium pressures at a certain temperature were observed for the reaction: N2 (g) + 3H2 (g) â 2NH3 (g)

PNH3 = 3.1 E^-2 atm
PN2 = 8.4 E^-1 atm
PH2 = 3.1 E^-3 atm

Required:
a. Calculate the value of the equilibrium constant Kp at this temperature.
b. How would you find K if the reaction were reversed?
