1. From the Haber synthesis, at the start of a reaction there are 0.489 mol N₂, 8.50 X 10-² mol H₂ and 2.50 X 10-4 mol NH3 in a 5.0 L reaction vessel at 325°C. If the equilibrium constant Kc for the reaction is 1.15 at this temperature, decide whether the system is at equilibrium. If it is not, predict which direction the net reaction will proceed. Hint: You need to write balanced molecular equation for this reaction.
