Both reactions are the examples of reversible reaction and the reaction moves both forward and backward direction.
In the first equation, hydrogen monoxide molecule is broken down into water and oxygen molecule. These two molecules again converted into hydrogen monoxide due to reversible reaction and gets equilibrium.
While on the other hand, in the second equation, oxygen molecule turns into ozone molecule and this ozone molecule again converted into oxygen molecule due to reversible reaction and attains equilibrium.
So we can conclude that both reactions are the examples of reversible reaction and the reaction moves both forward and backward direction.
