Question

$2{\mathrm{CO}}_2\left(g\right)+2H_2\left(g\right)\to 2\mathrm{CO}\left(g\right)+2H_{2}O\left(g\right)$
In this reaction ______ is getting oxidised.

• A. ${\text{CO}}_2$
• B. ${\text{H}}_2\text{O}$
• C. ${\text{H}}_2$
• D. $\text{CO}$

Answer 1

The correct option is C ${\text{H}}_2$

In the given reaction, carbon dioxide (${\text{CO}}_2$) is reacting with hydrogen to form carbon monoxide and water. Here hydrogen (${\text{H}}_2$) is getting oxidised as it gaining an oxygen atom to form water (${\text{H}}_2\text{O}$).
