Can someone pls help lol What would happen to a gas if you could infinitely keep increasing the pressure? (assume the structure of the container will not break under super-high pressure)?

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?
