Question

The amount of CO₂ generated (in kg) while completely oxidizing one kg of CH₄ to the end products is _________

Answer 1

Molecular wt. of CH₄ is 16 gm

Molecular wt. of CO₂ is 44 gm

When CH₄ reacts with O₂, leads to formation of CO₂ and H₂O. The reaction involved is:

\(C{H_4} + 2{O_2}\;\mathop \to \limits^{{\rm{\;\Delta }}\;} C{O_2} + 2{H_2}O\)

1 mole of CH₄ gets completely oxidized and formed 1 mole of CO₂

⇒ 16 gm of CH₄ → formation of 44 gm CO₂

1 gm of CH₄ → formation of \(\left( {\frac{{44}}{{16}}} \right)gm\;C{O_2}\)

1000 gm of CH₄ → formation of \(\frac{{44}}{{16}} \times 1000 = 2750\;C{O_2}\)

∴ CO₂ formed is 2.75 kg
