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?
Higher rate of reaction and decreased yield of ammonia.
Lower rate of reaction and increased yield of ammonia.
Lower rate of reaction and decreased yield of ammonia.
Higher rate of reaction and increased yield of ammonia.
