Answer:

H2

Step-by-step explanation:

N2 + 3H2 - - > 2NH3

3mol 5mol

So, 3 moles of N2 (or 6 moles of N) will be moved to the right side.

5 moles of H2 (or 10 moles of H) will be moved to the right side.

NH3 requires 1 N and 3 H.

N: 6mol/1(mole needed)= #recipes

= 6 possible recipes

H: 10mol/3(moles needed) = #recipes

= 3.33 possible recipes

Nitrogen can make more recipes, and is being limited by hydrogen.
