Hydrogen peroxide, H2O2, decomposes according to the equation above. This reaction is thermodynamically favorable at room temper
s2008m [1.1K]

Answer:

4H₂O₂ → 4H₂O + 2O₂

Explanation:

The chemical reaction for the decomposition of hydrogen peroxide can be represented as follows;

2H₂O₂ → 2H₂O + O₂

Therefore, two molecules of hydrogen peroxide decomposes into two molecules of water and one molecule of oxygen.

In a related diagram, we have 4 molecules of hydrogen peroxide decomposing, therefore we have;

4H₂O₂ → 4H₂O + 2O₂

The attached diagram shows the products of the decomposition of the four molecules of hydrogen peroxide.
