For the reaction. 2H2 g+O2 g2H2O g, at 300 K, ΔG and ΔH of water are -228.4 kJ.mol-1  and -241.60 kJ.mol-1, respectively. Then calculate the value of change in entropy for the given reaction.

  1. A +88 J/K
  2. B +4.4 kJ/K
  3. C -88 J/K
  4. D -44 J/K
Verified Solution

Answer & Solution

Correct Answer

(D) -44 J/K

Step-by-step Solution

Detailed explanation

From the relation of thermodynamics, we have, ∆S= ∆H - ∆GT = -241.6 -(-228.4) × 103300 = -44 J/K
