Question #776a4

Answer 1

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 `NF_3`.

`3H_2 + 2NF_3 → 6HF + N_2`

Therefore 5.5 moles of `H_2` would react with
`(2/3)*5.5 = 3.67`moles of `NF_3`.
