Homogeneous Reactions. At equilibrium, the rate of the forward and reverse reaction are equal, which is demonstrated by the arrows. The equilibrium constant, however, gives the ratio of the units (pressure or concentration) of the products to the reactants when the reaction is at equilibrium.
Answer:
The new pressure becomes one third of the initial pressure.
Explanation:
The relation between pressure and volume at constant temperature is given by :

Let new pressure and volume be P' and V' respectively.
V'=3V (given)
So,

Hence, new pressure becomes one third of the initial pressure.
