Question 9

The Haber process produces ammonia, NH3\text{NH}_3NH3​, in an exothermic reaction:

N2(g)+3H2(g)⇌2NH3(g) \text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g}) N2​(g)+3H2​(g)⇌2NH3​(g)

The temperature in the reactor is usually around 450∘C450^\circ\text{C}450∘C.

What happens to the rate of reaction and the yield of ammonia as the temperature is decreased to 350∘C350^\circ\text{C}350∘C?

A

Higher rate of reaction and decreased yield of ammonia.

B

Lower rate of reaction and increased yield of ammonia.

C

Lower rate of reaction and decreased yield of ammonia.

D

Higher rate of reaction and increased yield of ammonia.
