Predict the sign of the entropy change, ΔS, for the following processes. Explain the reason for each of the predictions.
Nastasia [14]

The sign of the entropy change, ΔS, for the following processes include:

  • I2 (s) + ½ Cl2 (g) ← → ICl (g) - positive
  • 3 Ag (s) + 4 HNO3 (aq) → 3AgNO3 (aq) + NO (g) + 2 H2O (l) - positive
  • Cl2 (g) → Cl2 (l) - negative
  • C5H12 (g) + 8 O2 (g) → 5 CO2 (g) + 6 H2O (l) - negative

What is Entropy?

This is referred to the degree of randomness or disorderliness of a system and is denoted as S.

Entropy change is usually positive when solid or liquid reactant is converted into gas product and vice versa.
