Process that does not involve a catalyst
The correct option is (B) Thermite process, which does not involve a catalyst.
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. Many chemical processes involve the use of catalysts to increase the efficiency of the reaction. However, some processes do not require the use of a catalyst.
Let's understand each of the processes mentioned in the options:
a) Haber's process: This process is used to produce ammonia from nitrogen and hydrogen gas. The reaction is very slow at room temperature and requires a catalyst (iron) to increase the rate of reaction.
b) Thermite process: This process involves the reaction of metal oxides with aluminum to produce metals. This reaction is highly exothermic and does not require a catalyst.
c) Ostwald process: This process is used to produce nitric acid from ammonia. The reaction is slow at low temperatures and requires a catalyst (platinum) to increase the rate of reaction.
d) Contact process: This process is used to produce sulfuric acid from sulfur dioxide. The reaction requires a catalyst (vanadium pentoxide) to increase the rate of reaction.
Therefore, the correct option is (B) Thermite process, which does not involve a catalyst.
