## Introduction

In chemistry, oxidation-reduction (redox) reactions involve the transfer of electrons between reactants, resulting in changes in their oxidation states. Nitrogen trioxide (N2O3) is a molecule that can act as both an oxidizing and a reducing agent, undergoing disproportionation (also known as dismutation) reactions. In this article, we will explore the redox reactions of nitrogen trioxide and the balanced equation for its disproportionation reaction.

## Redox Reactions of Nitrogen Trioxide

Nitrogen trioxide can undergo both reduction and oxidation reactions, as shown below:

*NIII + e- → NII (reduction)*

*NIII - 1 e- → NIV (oxidation)*

## Disproportionation of Nitrogen Trioxide

N2O3 can also undergo a disproportionation (dismutation) reaction, in which it is both oxidized and reduced to form nitric oxide (NO) and nitrogen dioxide (NO2):

*N2O3 → NO + NO2*

## Balancing the Equation

To balance the chemical equation for the disproportionation of nitrogen trioxide, we can use stoichiometric coefficients. Setting the coefficient for N2O3 to 1, we can solve for the coefficients of NO and NO2:

*N2O3 → NO + NO2*

Using the conservation of mass, we can set up the following system of equations:

*N: 2(1) = C2 + C3*

*O: 3(1) = C2 + 2(C3)*

Solving for C2 and C3, we get:

*C2 = 1*

*C3 = 1*

Substituting the coefficients back into the equation, we get:

* N2O3 → NO + NO2*
