If the system below is at equilibrium in a closed vessel and the vessel was heated, what would be expected to happen? HN3(l) 2 H2O(l) <--> N2H4(l) + HNO2(l) ?Hº = +641 kJ Question 3 options: a. The equilibrium amounts would stay the same b. the equilibrium would shift to the right making more reagents c. the equilibrium would shift to the left making mroe reagents d. the equilibrium would shift to the right making more products e. the equilibrium would shift to the left making more products
