If the system below is at equilibrium in a closed vessel and the size of the vessel was decreased, what would be expected to happen? HN3(l) 2 H2O(l) <--> N2H4(l) + HNO2(l) ?Hº = +641 kJ. the equilibrium would shift to the right producing more products the equilibrium would shift to the left producing more reagents the equilbrium would not be effected by the created pressure change the equilibrium would speed up the equilibrium would shift to the right side since it contains less molecules
