AIIMS 2019 Chemistry Synthesis Gas MCQ Question

Type: MCQ-conceptual-Medium-Class 11

An equimolar mixture of CO and H₂ is obtained when steam is passed over red hot coke. It is also named as syn gas. The reaction is, H₂O(g) + C → CO + H₂

Correct Answer

Option D

Detailed Explanation

The reaction H2O(g)+CCO+H2\text{H}_2\text{O}(g) + \text{C} \rightarrow \text{CO} + \text{H}_2 describes the process of gasification, where water vapor reacts with carbon (coke) to produce carbon monoxide (CO) and hydrogen gas (H₂), collectively known as synthesis gas or syngas. Option D is correct as it accurately identifies the products of the reaction, which are essential in various industrial applications, including the production of fuels and chemicals. Other options are not applicable as they do not provide relevant information or alternatives related to the reaction or its products.
