For the exothermic reaction n2(g)+3h2(g)→2nh3(g) what will happen if hydrogen gas was removed from the reaction mixture?

Answer is: There will be a shift toward the reactants.

Balanced chemical reaction: N₂ + 3H₂ ⇄ 2NH₃.

According to Le Chatelier's Principle the position of equilibrium moves to counteract the change.

According to Le Chatelier's principle: if the concentration is changed, that will shift the equilibrium to the side that would reduce that change in concentration.

The equilibrium shift to the left, so more hydrogen will be produced.

these nuts

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions
