Question

given the following equation select the appropriate stoichiometric ratio between no and nh₃: 2 no(g) + 5 h₂(g) → 2 nh₃(g) + 2 h₂o(g) 1 mol no : 1 mol nh₃ 2 mol no : 2 mol nh₃ 5 mol no : 1 mol nh₃ 2 mol no : 1 mol nh₃

Explanation:

Step1: Identify coefficients

In the equation $2NO(g)+5H_2(g)
ightarrow2NH_3(g) + 2H_2O(g)$, the coefficient of $NO$ is 2 and the coefficient of $NH_3$ is 2.

Step2: Determine ratio

The stoichiometric ratio of $NO$ to $NH_3$ is based on their coefficients. So the ratio is $2\ mol\ NO:2\ mol\ NH_3$.

Answer:

2 mol NO : 2 mol NH₃
