(A): In the Haber process, $\mathrm{N}_{2}+3 \mathrm{H}_{2} \leftrightarrow 2 \mathrm{NH}_{3}$ Pressure is about 200 atm in presence of catalyst and temperature is kept $500^{\circ} \mathrm{C}$ even the reaction is exothermic. (R): Energy needed for this reaction is easily obtained at this temperature.
In the Haber process for the industrial manufacturing of ammonia, involving the reaction N2(g) + 3H2(g) → 2NH3(g) at 200 atm pressure in the presence of a catalyst, a temperature of about 500°C is used. This is considered the optimum temperature for the process because: A. The yield is maximum at this temperature. B. The catalyst is active only at this temperature. C. The energy needed for the reaction is easily obtained at this temperature. D. The rate of the catalytic reaction is fast enough, while the yield is also appreciable for this exothermic reaction at this temperature.
