51. In the Haber process for the industrialmanufacturing of ammonia involvingthe reaction,N2(g) + 3H2(g) + 2NH3(g) at 200atmpressure in the presence of acatalyst, a temperature of about 500°Cis used. This is considered as optimumtemperature for the process because(1) yield is maximum at thistemperature(2) catalyst is active only at thistemperature(3) energy needed for the reaction iseasily obtained at this temperature(4) rate of the catalytic reaction is fastenough while the yield is alsoappreciable for this exothermic reactionat this temperature. |
