1.3 3 (ii) In the Haber process for the production of ammonia the following reaction occurs: N2(g) + 3H2(g) 2NH3(g) ΔΗ is negative If the equilibrium concentrations for all the reactants and products at 600°C are: [N₂] = 0.40 mol/dm³, [H₂] = 1.20 mol/dm³ and [NH3] = 0.20 mol/dm³ what is the numerical value of the equilibrium constant, Kc? (iii) At 500°C Kc = 0.062 mol-2dm. Compare this value to the one you calculated in 3 (ii) above and state whether the yield of ammonia is greater at 500°C or 600°C and briefly explain your choice.
