Question

At 450 °C, the Kp for the reaction N2(g) + 3 H2(g) 2NH3(g) is 4.5 x 10-5. For each mixture listed, indicate whether the mixture is at equilibrium at 450 °C. If it is not at equilibrium, indicate the direction (toward product or toward reactants) in which the mixture must shift to achieve equilibrium.

a. 98 atm NH3, 45 atm N2, 55 atm H2

b. 57 atm NH3, 143 atm N2, 79.6 atm H2

c. 13 atm NH3, 172 atm N2, 82 atm H2
