Today, we're diving into the concept of water gas, which primarily consists of carbon monoxide and hydrogen. Can anyone tell me why hydrogen is a crucial element in our industrial processes?
Hydrogen is used to make ammonia and other chemicals, right?
Exactly! Hydrogen is essential for the Haber process, which synthesizes ammonia. Now, water gas is produced by passing steam over red-hot coke. Can anyone explain what coke is?
Coke is a solid carbonaceous material produced by heating coal without air.
Right! This reaction gives us a mixture of hydrogen and carbon monoxide. That's the essence of water gas. Remember that water gas plays a critical role in producing hydrogen for various chemical reactions.

Quick Overview
Standard
This section discusses water gas as a crucial source of hydrogen in industrial applications. Water gas, consisting of carbon monoxide and hydrogen, is generated through a reaction between steam and red-hot coke, and it serves various purposes in ammonia production and organic chemistry.
Detailed
Detailed Overview of Water Gas (CO + H₂)
Water gas, a mixture primarily composed of carbon monoxide (CO) and hydrogen (H₂), is a significant industrial source of hydrogen. To produce water gas, steam is passed over red-hot coke, which triggers an endothermic reaction. The reaction can be represented by the equation:
$$C + H_2O \rightarrow CO + H_2$$
This method of hydrogen production is pivotal for various applications, particularly in the syntheses of ammonia and organic compounds. Due to its composition, water gas emphasizes the dual-functionality of hydrogen as both an energy source and a chemical reactant, showcasing its relevance in sectors that demand hydrogen for the production of fuels and chemicals.

Chapter Content
Produced by passing steam over red-hot coke.
$$\text{C} + \text{H}_2\text{O} \rightarrow \text{CO} + \text{H}_2$$
Detailed Explanation
Water gas is produced through a chemical reaction where steam interacts with red-hot coke (which is a form of carbon). This process can be summarized by the equation where carbon (C) reacts with water (H₂O) to yield carbon monoxide (CO) and hydrogen gas (H₂). The reason we use red-hot coke is that it helps to facilitate this reaction effectively, providing the necessary heat to drive the reaction forward.
Examples & Analogies
Think of red-hot coke as a barbecue grill. Just as grilling food requires a hot grill to cook properly, the reaction needs the coke to be hot enough to kickstart the conversion of steam into hydrogen and carbon monoxide.

Chapter Content
- Starting Materials: Red-hot coke (carbon) and steam (water vapor).
- Products: Hydrogen gas (H₂) and carbon monoxide (CO).
- Exothermic Nature: The reaction releases heat, which indicates that it is exothermic.
Detailed Explanation
In the water gas production process, the starting materials are red-hot coke and steam. As they react, they produce two gases: hydrogen and carbon monoxide. This reaction is exothermic, meaning it releases heat as a byproduct, which can be used in various applications - including maintaining the temperature of the reaction to keep it going efficiently.
Examples & Analogies
Consider how wood burns in a fire. As logs heat up and react with oxygen, they produce heat and flames, which can warm your hands or cook food. Similarly, the reaction in water gas production generates heat that can be harnessed for other purposes, just like a campfire.
