H₂O + C → H₂ + CO

The above reaction is an example of

Correct option is B

The correct answer is (b) Water gas reaction

Explanation:

• The reaction of steam (H₂O) with red-hot coke (C) at high temperatures produces a mixture of Hydrogen (H₂) and Carbon Monoxide (CO).
• This mixture (H₂ + CO) is commonly known as Water Gas or Synthesis Gas (Syngas).
• It is an endothermic process and is used industrially to produce hydrogen.
• The process is also referred to as coal gasification.

Information Booster:

• Producer Gas is a mixture of CO and N₂, formed by passing air over hot coke.
• Water gas is used as a fuel and as a starting material for the synthesis of methanol and various hydrocarbons.

Additional Knowledge:

Ziegler-Natta process (Option a)

• Used for the polymerization of olefins (like polyethylene) using special catalysts.

Wacker process (Option d)

• An industrial method to produce acetaldehyde from ethylene.

So the correct answer is (b)
