We’re being asked to** calculate the standard entropy change** for the following reaction:

N_{2} (g) +3 F_{2} (g) → 2 NF_{3} (g)

We can use the following equation to solve for **ΔS˚ _{rxn}**:

$\overline{){\mathbf{\Delta S}}{{\mathbf{\xb0}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{S}}{{\mathbf{\xb0}}}_{\mathbf{f}\mathbf{,}\mathbf{}\mathbf{prod}}{\mathbf{-}}{\mathbf{S}}{{\mathbf{\xb0}}}_{\mathbf{f}\mathbf{,}\mathbf{}\mathbf{react}}}$

For each reaction, find the value of delta S. Report the value with the appropriate sign.

b) N_{2} (g) +3 F_{2} (g) → 2 NF_{3} (g)
