Question

Evaluate each reaction below and using your knowledge of entropy, predict whether entropy will increase or decrease as reactants are converted to products.

Reaction	Will entropy increase or decrease?
2 NH₃(g) → N₂(g) + 3 H₂(g)	increase or decrease
PbS(s) → Pb²⁺(aq) + S^2-(aq)	increase or decrease
CH₄(g) + 2 O₂(g) → CO₂(g) + 2 H₂O(l)	increase or decrease
N₂(g) + 3 H₂(g) → 2 NH₃ (g)	increase or decrease
