# Question 776a4

3.67

#### Explanation:

This is really not a very reactive combination. http://www.sciencedirect.com/science/article/pii/0022236473900036

But, based on the available reaction mechanisms, and assuming complete reaction. The stoichiometry shows a 3:2 ratio of ${H}_{2}$ to $N {F}_{3}$.

3H_2 + 2NF_3 → 6HF + N_2#

Therefore 5.5 moles of ${H}_{2}$ would react with
$\left(\frac{2}{3}\right) \cdot 5.5 = 3.67$moles of $N {F}_{3}$.
