第 1 题
1

In the industrial manufacture of ammonia via the Haber process, nitrogen and hydrogen react according to the following equation:
\(\text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g})\)

Which set of conditions is typically used in the reactor to achieve an optimal balance between the rate of reaction and the yield of ammonia?

第 2 题
1

Ammonia is produced industrially using the Haber process. Which statement correctly describes the source of a raw material or a characteristic of this process?

第 3 题
1

In a Haber process simulation, \( 40 \text{ cm}^3 \) of nitrogen gas is reacted with \( 60 \text{ cm}^3 \) of hydrogen gas. If the reaction achieves a \( 40\% \) yield based on the limiting reactant, what is the volume of ammonia produced? (Assume all gas volumes are measured at the same temperature and pressure.)

第 4 题
1

In the industrial manufacture of ammonia via the Haber process, which of the following substances is used as a catalyst to increase the rate of reaction?

第 5 题
1

Which balanced chemical equation correctly represents the reaction between aqueous ammonia and dilute sulfuric acid to form a salt?

第 6 题
4

When ammonia gas is passed over heated copper(II) oxide, a reddish-brown solid, water vapour, and a colourless gas are formed.

Identify the colourless gas and write a balanced chemical equation for this reaction, including state symbols.
