Calculate the change in Entropy (ΔS) for a reaction given the following information:
Reaction: N2(g) + 3H2(g) → 2NH3(g)
ΔS° (N2(g)): 191.5 J/(mol·K)
ΔS° (H2(g)): 130.6 J/(mol·K)
ΔS° (NH3(g)): 192.5 J/(mol·K)
ΔS = 2 × ΔS° (NH3(g)) - [ΔS° (N2(g)) + 3 × ΔS° (H2(g))]
= 2 × (192.5 J/(mol·K)) - [191.5 J/(mol·K) + 3 × 130.6 J/(mol·K)]
= 71.7 J/(mol·K)
