The following equilibrium pressures were observed at a certain temperature for the reaction. N2(g) + 3 H2(g) 2 NH3(g) PNH3 = 3.1 10-2 atm PN2 = 8.5 10-1 atm PH2 = 3.1 10-3 atm a)Calculate the value for the equilibrium constant Kp at this temperature. atm-2 If PN2 = 0.516 atm, PNH3 = 0.0172 atm, and PH2 = 0.00775 atm, b) does this represent a system at equilibrium? Yes No c) Give the value for the Kp expression using the partial pressures to support your answer. atm-2
