The Haber process demonstrates that commercial processes do not maximize each factor that affects equilibria but use them in combination to get maximum production. Which of the following statements about the Haber process is false?
N2(g) + 3H2(g) 2NH3(g) + 92.24 kJ
a. Although Kc is much greater at 25°C, the reaction is carried out at 450°C.
b. A catalyst is used to increase reaction rate.
c. Although the reaction is exothermic, it is carried out at high (450°C) temperature.
d. Although high pressure is unfavorable to the production of the NH3(g), the reaction is carried out under a pressure of 200−1000 atmospheres.
e. The emerging reaction mixture is cooled to remove the NH3 and the N2 and H2 recycled.
Answer: d. Although high pressure is unfavorable to the production of the NH3(g), the reaction is carried out under a pressure of 200−1000 atmospheres.
