How does NO2 become N2O4?

According to the thermodynamic data for this system, the dimerization of NO2 (shown below) is an exothermic reaction. … Conversely, cooling the reaction shifts the equilibrium to the right, producing more N2O4 which is colorless.

Is N2O4 to NO2 exothermic or endothermic?

This reaction is exothermic in the forward reaction (produces N2O4), and endothermic in the reverse reaction (produces NO2).

What type of reaction is 2NO2 → N2O4?

It is a redox reaction.

What is the decomposition of N2O4?

Problem: The decomposition of N2O4 at 25°C, N2O4(g) ⇌ 2NO2(g) has Kc = 4.61 x 10-3.

What is the stoichiometric ratio of NO2 to N2O4?

4.63 The simplest ratio, that is, [NO2]/[N2O4], gives scattered values. But if we examine other possible mathematical relationships, we find that the ratio [NO2]2/[N2O4] at equilibrium gives a nearly constant value that averages 4.63.

How is N2O4 formed?

Dinitrogen tetroxide (N2O4) is a diamagnetic colorless toxic gas that is formed when two nitrogen dioxide molecules (NO2) react with each other in a process called dimerization.

Is N2O4 G 2no2 G exothermic?

In 2NO2(g) ↔ N2O4(g) ΔH = -58.0 kJ/mol N2O4: Being that the reaction as written is exothermic (heat is produced in the forward reaction) we can expect that an increase in temperature in this system will cause the reaction to shift reverse (favor the endothermic reaction) to use the excess heat.
