N2(g) + 3H2(g) <---> 2NH3(g) nh3 was synthesized at 200C in the presence of a powdered os catalyst leading to the equilibrium system represented above. Which of the following would result in more NH3 in the mixture after equilibrium is reestablished
A) Adding some N2(g)
B) Removing some H2(g)
C) increasing the temperature of the system to 250C at a constant pressure
D) replacing the powdered Os(s) with a solid cube of Os(s) of the same total mass

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
