  1. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g)

  2. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible

  3. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible 2K+ (aq) + 2OH–(aq) + H2 (g) → 2K (s) + 2H2O

  4. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible 2K+ (aq) + 2OH–(aq) + H2 (g) → 2K (s) + 2H2O impossible

  5. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible 2K+ (aq) + 2OH–(aq) + H2 (g) → 2K (s) + 2H2O impossible N2 + 3H2 → 2NH3

  6. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible 2K+ (aq) + 2OH–(aq) + H2 (g) → 2K (s) + 2H2O impossible N2 + 3H2 → 2NH3

  7. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible 2K+ (aq) + 2OH–(aq) + H2 (g) → 2K (s) + 2H2O impossible N2 + 3H2 → 2NH3 forward N2 + 3H2 ← 2NH3 backward

  8. Disorder created in surroundings Disorder created in system O2 + 2H2 → 2H2O irreversible Ba(OH)2 (s) + 2NH4Cl (s) → 2H2O + 2NH3 (g) + Ba2+ (aq) + 2Cl– (aq) irreversible 2K (s) + 2H2O → 2K+ (aq) + 2OH–(aq) + H2 (g) irreversible 2K+ (aq) + 2OH–(aq) + H2 (g) → 2K (s) + 2H2O impossible N2 + 3H2 → 2NH3 forward The reaction occursreversibly. N2 + 3H2 ← 2NH3 backward
