Q2) Ammonia production is important in industry. N2 (g) + 3H2 (g) = 2NH3 (g) AH=-92 kJ mol a) Determine the value of the equilibrium constant at 298 K by using the value of AG =31.84 KJ b) 0.20 mol of N2 (g) and 0.20 mol of H2 (g) were allowed to reach equilibrium in a 1 dm closed container at a temperature T2, which is different to 298 K. At equilibrium the concentration of NH3 (g) was found to be 0.060 mol dm, Determine the value of Kc at temperature T21, c) Comment on the two different values for Kc obtained in part a and b.
