Question

Write the names of the catalysts used in contact process and Ostwald process.

Hint:

Vanadium(V) oxide is used in the Contact Process due to its ability to facilitate the oxidation reaction. Platinum is used in the Ostwald Process due to its catalytic properties in high-temperature reactions.

Answer 1

Step 1: Understand the Contact Process.
In the Contact Process, the catalyst used is Vanadium(V) oxide (\( V_2 O_5 \)). This catalyst helps in the oxidation of sulfur dioxide to sulfur trioxide.
Step 2: Understand the Ostwald Process.
In the Ostwald Process, the catalyst used is Platinum or Platinum-Rhodium alloy. This catalyst is used for the oxidation of ammonia to nitric oxide.
Final Answer: For the Contact Process: Vanadium(V) oxide (\( V_2 O_5 \))
For the Ostwald Process: Platinum or Platinum-Rhodium alloy
Final Answer: \[ \boxed{Vanadium(V) oxide (\,V_2 O_5\,), Platinum or Platinum-Rhodium alloy} \]
