Why is a higher temperature used in the haber process?
Although it decreases the yield of ammonia, it speeds up the rate of reaction. It's a compromise between yield and rate
Why is a pressure of 200 atmospheres used in the haber process?
Although it decreases the yield, operating at higher pressures is expensive and increases risk of explosions. It is a compromise between yield and cost/safety
Why does the iron catalyst eventually need to be replaced in the haber process?
