(NEEDED ASAP) question is in the description

Question

given the reaction at equilibrium N₂(g) + 3H₂(g) ↔ 2NH₃(g)

what is the mole-to-mole ratio between nitrogen gas and hydrogen gas?

1. 1: 2
2. 1: 3
3. 2 : 2
4. 2 : 3

Answer 1

Hello, Pi,

The coefficients of the balanced equation state that there will be three moles of hydrogen for every one mole of nitrogen. So the ratio of H₂/N₂ is 3/1, and, conversely, N₂/H₂ is 1/3.
