CAPE Chemistry Unit 2 · 2017 · Paper 1 · Question Q33
From the reaction given below, a high pressure would give the best yield, but in industry, a moderate pressure is used.
\text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g})
Why is a moderate pressure used in industry rather than high pressure?
- (A)It is too expensive to produce high pressure.
- (B)The reaction would be uncontrollably fast.
- (C)The reaction would be too slow to generate adequate
\text{NH}_3. - (D)It is easier to remove the
\text{NH}_3from the reaction container.
