A chemical reaction between X2 and Y2 produces XY. All compounds are in a gaseous state. Consider that you have the following mixture of species in your reaction vessel at a given time: X2 : 19 molecules Y2 : 17 molecules XY : 46 molecules Calculate the equilibrium constant for the balanced reaction between one mole of each reagent.
