JEE Main 2023Hydrogen Question with Solution

JEE Main 2023 (10 Apr Shift 1)

Question

Given below are two reactions, involved in the commercial production of dihydrogen H2. The two reactions are carried out at temperature “T1” and “T2”, respectively

Cs+H2OgT1COg+H2g

COg+H2OgT2CatalystCO2g+H2g

The temperatures T1 and T2 are correctly related as

Choose an option

Show full solutionCorrect option: D
Correct answer
DT1>T2

Step-by-step explanation

Cs+H2Og1270 K T1COg+H2g is known as coal gasification reaction. The mixture produced in this reaction is called water gas.

COg+H2Og673 K T2CatalystCO2g+H2g is known as water gas shift reaction. Using water gas shift reaction we can increase the concentration of hydrogen gas.

Hence, T1>T2
