The correct equation showing the decomposition of NO2 is:

2NO2(g)2NO(g) + O2(aq)

Explanation:

We can know it's a decomposition reaction because a single reactant forms two simpler products. In this case, the NO2 loses oxygen. For every two moles of NO2 decomposed, two moles of oxygen atoms are lost, which form one mole of oxygen gas (O2).
