Thermo Chem question

Question

What is the thermochemical equation for the formation of 2.5 mol of NH₃(g) from H₂(g) and N₂(g)?

First, enter the chemical equation:

Then determine ΔH

Answer 1

3H₂(g) + N₂(g) ==> 2NH₃(g) ... This is the balanced equation for the formation of NH₃(g) from H₂(g) and N₂(g)

If you want to form 2.5 moles of NH3, all coefficients need to be multiplied by 1.25 to yield

3.75 H2(g) + 1.25N2(g) ==> 2.5 NH3(g)

There isn't enough information provided to allow determination of ∆H
