According to le chatelier's principle how will a pressure increase affect a gaseous system

According to Le chatelier's principle an increase in pressure would affect a gaseous system in that; the side of the equilibrium with fewer moles of gases is more favorable and with a decrease in pressure in volume, the side with more moles is more favorable. Additionally; changing the pressure of a system containing gases in equilibrium may result in the position of equilibrium only if there are more gaseous molecules on one side of the equation than the other.

The total number of gas molecules will decrease
