✓
Answer
- In industries some chemical substances are used to alter the speed of a chemical reaction. These substances are called catalysts.
- For example, metallic iron is used as a catalyst in the manufacture of ammonia using Haber’s process.
- This ammonia is the basic material for the production of urea, an important fertilizer in agriculture.
- In Vanaspati ghee (dalda) preparation finely divided nickel is used as a catalyst.
- Thus, speed of the certain reactions is influenced by the catalysts and such reactions are called catalytic reactions.
- Enzymes and yeasts are called biocatalysts.
