The reverse direction is favored; formation of reactants.
Explanation:
Hello,
In this case, when the chemical reactions are being carried out in gaseous phase, the pressure has a significant effect if the number of moles of reactants differ from those of the products favoring the equilibrium towards the direction having the fewer amount of moles.
In such a way, if the moles of the reactants are less than those of products, increasing the pressure will reverse the reaction towards reactants again as equilibrium shall be reestablished.
