A container was charged with hydrogen, nitrogen, and ammonia gases at 120°C and the system was allowed to reach equilibrium. What will happen if the volume of the container is increased at constant temperature? 3H2(g) + N2(g) ⇌ 2NH3(g) The equilibrium constant will decrease. Hydrogen and nitrogen will be produced at the expense of ammonia. There will be no effect. The equilibrium constant will increase. More ammonia will be produced at the expense of hydrogen and nitrogen.
