5.4 In Haber’s process, hydrogen is obtained by reacting methane with steam in presence of NiO as catalyst. The process is known as steam reforming. Why is it necessary to remove CO when ammonia is obtained by Haber’s process?
Answer It is important to remove $\mathrm{CO}$ in the synthesis of ammonia as $\mathrm{CO}$ adversely affects the activity of the iron catalyst, used in Haber’s process.Show Answer
Answer Ester hydrolysis can be represented as: Ester + Water $\longrightarrow$ Acid + Alcohol The acid produced in the reaction acts as a catalyst and makes the reaction faster. Substances that act as catalysts in the same reaction in which they are obtained as products are known as autocatalysts.Show Answer
