Consider this reaction taking place in a closed container: 2N2(g) + 3H2(g) → 2NH3(g)

If you wanted to increase the yield of ammonia, according to le Châtelier’s principle, you could

A)add a catalyst.
B)increase the pressure.
C)increase the size of the container.
D)decrease the number of moles of nitrogen.

The answer options is d

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
