Problem
At 500 K the equilibrium constant for ammonia synthesis is Kp=0.15 for the reaction N2(g)+3H2(g)↔2NH3(g). Initially, the system is at equilibrium with pN2=1.0atm, pH2=3.0atm, and pNH3=2.0atm. The volume of the container is suddenly halved (temperature constant). Calculate the new reaction quotient Qp immediately after compression and state whether the reaction will shift toward reactants or products to re-establish equilibrium.
