Question

hydrogen peroxide undergoes a decomposition reaction inside rocket booster to provide necessary conditions for burning of rocket fuel.

what is the products obtain during this decomposition reaction?
1.h2o2=h2o+h2+triangle
2.h2o2=h2o+triangle
3.h2o2=h2+o2+h2o
4.h2o=h2o+o2+triangle

Answer 1

Answer:

option 3rd is the right answer

Answer 2

Answer:

Option (4) H₂O₂→ H₂O + O₂ + Δ is correct.

Explanation:

• Hydrogen peroxide decomposes to water and oxygen in presence of warm conditions or the presence of UV light.

• The O-O bond in the molecule is quite unstable.  

• The rate of reaction is slow at a moderate pH and temperature; and can be sped up upon the addition of a catalyst or increasing the temperature.

• It is a highly exothermic reaction due to the formation of new bonds. The heat produced can also lead to further increment in thermal decomposition.
• This heat energy helps in burning of rocket fuel.
• H₂O₂→ H₂O + O₂ + Δ

Conclusion:

The products obtained during decomposition of hydrogen peroxide are water and oxygen.
