26 & SEPT 20 (4/20 & 5/20)I.FOUNDATION IN SSEMESTER 2 FSC CHE 124 CHEMEQUESTION 6Le Châtelier's principle is frequently used in daily life. Le Châtelier's principle is anobservation about chemical equilibria of reactions. It states that changes in thetemperature, pressure, volume, or concentration of a system will result in predictableand opposing changes in the system in order to achieve a new equilibrium state. LeChâtelier's principle can be used in practice to understand reaction conditions that willfavor increased product formation.State one example of Le Châtelier's principle in home cooking.Explain the example given by using the Le Châtelier's principle in the examplegiven.

A gaseous material XY(g) dissociates to some extent to produce X(g) and Y(g): XY(g)X(g)+Y(g) A 2.00-g sample of XY (molar mass = 165 g/mol) is placed in a container with a movable piston at 25C. The pressure is held constant at 0.967 atm. As XY begins to dissociate, the piston moves until 35.0 mole percent of the original XY has dissociated and then remains at a constant position. Assuming ideal behavior, calculate the density of the gas in the container after the piston has stopped moving, and determine the value of K for this reaction of 25C.
