Question

Given below are two statements :
Statement I : The process of producing syn-gas is called gasification of coal.
Statement II : The composition of syn-gas is \( \text{CO} + \text{CO}_2 + \text{H}_2 \) (1 : 1 : 1).
In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Both Statement I and Statement II are true.
• B. Both Statement I and Statement II are false.
• C. Statement I is true but Statement II is false.
• D. Statement I is false but Statement II is true.

Hint:

Water gas and syn-gas have the same components: \( \text{CO} + \text{H}_2 \). Syn-gas is the term used when the mixture is destined for chemical synthesis (like methanol production).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Syn-gas (Synthesis gas) is a fuel gas mixture used as an intermediate in creating various chemicals and fuels.
Step 2: Detailed Explanation:
1. Statement I: The reaction of steam with coal at high temperature (\( \sim 1270 \, \text{K} \)) to produce synthesis gas is specifically known as coal gasification.
\[ \text{C}(s) + \text{H}_2\text{O}(g) \to \text{CO}(g) + \text{H}_2(g) \]
Thus, Statement I is true.
2. Statement II: Syn-gas is primarily a mixture of carbon monoxide (\( \text{CO} \)) and hydrogen (\( \text{H}_2 \)). While it may contain trace amounts of other gases, the "1:1:1" ratio including \( \text{CO}_2 \) is incorrect for the standard definition of syn-gas.
Thus, Statement II is false.
Step 3: Final Answer:
Statement I is true, while Statement II is incorrect.
