According to le châtelier's principle, how will an increase in pressure affect a gaseous equilibrium system? shift it toward the products shift it toward the reactants shift it toward the side with higher total mole concentration shift it toward the side with lower total mole concentration

Shift it toward the side with lower total mole concentration.

Explanation:

Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.When there is an increase in pressure, the equilibrium will shift towards the side with fewer moles of gas of the reaction. And when there is a decrease in pressure, the equilibrium will shift towards the side with more moles of gas of the reaction.So, the right choice is: Shift it toward the side with lower total mole concentration.
